The throttle, brake, their switch and potentiometers[[Adapter V2 manual&veaction=edit&section=3|edit]][[Adapter V2 manual&action=edit&section=3|edit source]]
Some ebike/escooters have 3 level throttles, VESC does not support 3 level.
Most throttle working on 5V, and output voltage up to 4.2V, VESC can only accept ADC input within 3.3V (3.44V for some hard ware version).
VESC supports analog brake (variable/propotional) input to its ADC2, common ebike/escooter only provide a electronic switch attached to mechanical brake.
The adapter V3 do these translating jobs, makes VESC a full functional ebike/scooter controller.
The adapter V3 divide the 5V range throttle, remap it to 3 levels, send to VESC ADC1; Simulate an analog brake voltage to the VESC ADC3 when the mechanical brake switch is triggered; Co-work analog brake input with mechanical brake. This dividing, remapping, and simulating can be adjust to require your demands with these switch and potentiometers:
The potentiometers are '''increase clockwise''' and '''decrease counterclockwise'''.
Throttle and brake power supply[[Adapter V2 manual&veaction=edit&section=4|edit]][[Adapter V2 manual&action=edit&section=4|edit source]]
If your throttle can only accept 3.3V supply, set the ‘HALL VDD’ switch to '3.3V' side. Otherwise set it to '5V'. The ADC brake port shares this supply too.
Throttle potentiometers[[Adapter V2 manual&veaction=edit&section=5|edit]][[Adapter V2 manual&action=edit&section=5|edit source]]
Adapter V3 supports three level throttles, the High level is equal to the throttle handle input. The middle and low level are remapped from throttle handle input according to the 'THR M' and 'THR L' potentiometer's positions. The remap range is from 0 to 100%.
'''If you are not connecting a three level throttle switch to adapter, in case you don't have it or don't need it, the default throttle level is middle, so adjust the''' '''<nowiki/>'THR M' potentiometer to its maximum position (clockwise), let the adapter not shrink the''' '''original throttle to''' '''the VESC.'''
'''Set 'M' and 'L' potentiometers to their maximum position (clockwise) when do the input setup on the VESC tool to avoid some confusion.'''
Brake potentiometer[[Adapter V2 manual&veaction=edit&section=6|edit]][[Adapter V2 manual&action=edit&section=6|edit source]]
Mechanical brake have a electronic switch, to tell ESC to stop driving, some ESC can then do regenrative braking.
When trigger the mechanical brake switch, adapter V3 will assist it with regenerative brake automatically, the regenerative brake strength is according to the 'BRK' potentiometer, from 0 to 100%. '''Set it to its maximum position when do the input setup on the VESC tool.'''
Analog/variable brake[[Adapter V2 manual&veaction=edit&section=7|edit]][[Adapter V2 manual&action=edit&section=7|edit source]]
When no actions happened from mechanical brake(no braking), adapter V3 will conduct the analog voltage from "ABRK" to the VESC ADC2 to support the analog/variable brake.
What if I don't want a regenerative brake?[[Adapter V2 manual&veaction=edit&section=8|edit]][[Adapter V2 manual&action=edit&section=8|edit source]]
So the ADC2 input is no needed for VESC, set the APP mode to "Current", set to "Current Reverse Button" mode if you need a reverse function.
The brake, throttle level, and trun left/right switch[[Adapter V2 manual&veaction=edit&section=9|edit]][[Adapter V2 manual&action=edit&section=9|edit source]]
The cruise, reverse, and horn inputs[[Adapter V2 manual&veaction=edit&section=10|edit]][[Adapter V2 manual&action=edit&section=10|edit source]]
The lights and horn output ports[[Adapter V2 manual&veaction=edit&section=11|edit]][[Adapter V2 manual&action=edit&section=11|edit source]]
Adapter's own Mode configuration[[Adapter V2 manual&veaction=edit&section=12|edit]][[Adapter V2 manual&action=edit&section=12|edit source]]
Adapter V3 has 2 mode configurations: '''two/one wheel drive mode switching, and one way/ two way throttle switching'''.
Two/one wheel drive mode switching[[Adapter V2 manual&veaction=edit&section=13|edit]][[Adapter V2 manual&action=edit&section=13|edit source]]
Hold both the right and left brake handles then power on the system, the adapter will toggle the 2/1 drive mode, after the switching, the buzzer will ring '''once for one wheel mode''', and '''twice for two wheel mode'''. Release both left and right brake.
The principle of 2 wheel drive is to copy the control signal from main ESC to the second ESC. In order to implement this function, the CAN bus connection of two ESCS need to set off, for Ubox dual, it has a internal CAN bus connection, please refer: [[The power button of Ubox#The click button configuration]].
'''Note: The new version firmware support a button to control the two/one wheel driving mode switching:'''
By connect the TX pin to the GND, the adapter will swtich to two wheel drive mode, will copy the throttle and brake signle from main socket to the secondary socket.
Two/one way throttle switching[[Adapter V2 manual&veaction=edit&section=15|edit]][[Adapter V2 manual&action=edit&section=15|edit source]]
Two way throttle is being referred as 'centered' throttle in VESC tool, it return to its center position when idle.
To change mode:
Hold both the left brake handle and the throttle handle bar, then power on the system, wait the buzzer ring '''three times, then still hold throttle and left brake 3 more seconds,''' until the buzzer '''again to ring 6 times''', release the throttle and left brake.
The setting entry is shared with power limit mode switching, so we need to wait the power limit mode setting being time out.
The difference between adapter's two/one way mode is, in one way mode, the throttle output to ESC is as same as throttle input, in two way mode, if the brake not triggered, throttle output to ESC is as same as throttle input; If the brake handle is triggered, it will replace the throttle output with the brake signal from the brake input.
Calibration for throttles (both vesc and non vesc)
Keep No power on status before entering in calibration mode.
1. Hold the left brake and throttle to max, then power on adapter (connected in esc by turning on esc), then adapter buzzer will beep 4times continuously, then loosing holding brake and throttle.
2. then red and green led lights will be flashing in the board
3. And Roll throttle to forward and backward repeatedly
4.Then hold the left brake again for 3seconds until the buzzer beep twice
5. Calibration ends, then push throttle to check if the throttle indication led light on green
Remark： Same process to calibrate the variable brake input, make sure to hold the variable brake to enter in calibration process.
Setup in VESC tool[[Adapter V2 manual&veaction=edit&section=16|edit]][[Adapter V2 manual&action=edit&section=16|edit source]]
Before setup control logic to the VESC, we need to setup motor's FOC first. The following contents are based on VESC tool 3.01 PC edition.
The setup input wizard of VESC tool 3.01 (FW 5.3) is easy to fail:
This is because there is too many data transfered on CAN bus when ESCs are bound to gether by CAN bus, the firmware check command is being blocked. '''Two solve this issue, we can reduce the CAN bus load by disable the secondary ESC's CAN status, then we set the main ESC's input separately first, then set the secdary ESC as salve on CAN bus manually.'''
For two wheel drive mode, the principle is set ADC input on main ESC (this guide will assign it to ESCA), then let the control signal relied to ESCB by CAN bus.
For two/one wheel drive switchable configuration, the principle is to turn off CAN bus connection, let the adapter to send the control single to the two ESCs separately.
For '''two way throttle''', we need to change the control mode in VESC to 'center' mode, we adopt the '<nowiki/>'''Current No Reverse Brake Center'''' mode in this guide. We also can do two/one wheel drive mode for two way throttle.
'''For one way throttle with regenerative brake, we adopt the 'Current Reverse ADC2 Brake Button' mode.'''
The Ubox dual has a internal 2.4G receiver, the receiver is no use in this application, we can disable receiver by click the button 9 times after the Ubox powered on and the button LED solid.
We will begin from one way throttle with two wheel drive mode. For the two/one drive switch-able mode, just disable the CAN bus connection and set the ADC control mode on the secondary ESC similar to main ESC . For the two way throttle, just set the control mode to 'Current No Reverse Brake Center'.
'''During the setup, the motor will spin even to full speed, keep every thing and every one away from the motor to avoid damage or injury.'''
Prepare[[Adapter V2 manual&veaction=edit&section=17|edit]][[Adapter V2 manual&action=edit&section=17|edit source]]
Refer the wiring picture to make wirings:
1.    Set the throttle and power supply switch to the voltage your throttle required on the adapter board.
2.    Set the brake potentiometer to its maximum positon (increase clockwise) on the adapter board.
3.    Set the throttle "M" and "L" potentiometers all to their maximum positon (increase clockwise) on the adapter board.
4.    Connect the throttle to the "GND", "THR“, "5V", respectively. '''Measure the "THR" voltage to the GND with a multimeter if you are not sure the wires are connected correctly or the throttle is defective'''. The voltage should be 0-0.8V when idle, and 3.5-4.2V when triggled.
5.    Connect the mechanical brake switch to the "L.BRK", "R.BRK" respectively if you have them.
6.    Connect the analog brake to the "G", "ABRK", "5V" respectively if you have a analog brake such as hall throttle, a potentiometer etc.
7.    For the cruise, horn, head light, they are working indepently from the VESC, so we can set them later.
Two wheel drive only mode with one way throttle on VESC tool PC edition[[Adapter V2 manual&veaction=edit&section=18|edit]][[Adapter V2 manual&action=edit&section=18|edit source]]
If you want 2 wheel drive only mode, you can config the two ESC of Ubox into CAN mode, let the control signals relay through the CAN bus.
'''If you don't use any machanical, analog brake for regenerative brake, to set the APP mode to "Current" , "Current Reverse center" or "Current Reverse Button" mode instead of "Current reverse ADC2 Brake Button" mode, the "Current Reverse Button" is suggested because it supports reverse fucntion.'''
1.After Ubox power on, and button LED solid, click the button 6 times, then wait 1 second, the internal CAN bus connection is on.
2. Do the FOC setup for both ESC.
3. Set the adapter V2 to one way throttle mode (default shipping mode), the Two/one wheel drive mode is meaningless in this configuration.
4.Plug in the ADC cable only from adapter's main socket to ESCA's socket.
5.'''Set you throttle handle bar's H-M-L switch to H position, if you don't have this switch, adjust the 'THR M‘ potentiometer to it max position (increase clockwise).'''
6. '''Set the brake potentiometer to max position,''' connect ADC (HALL or analog) brake if you have it.
7.Then use a USB cable plug into ESCA, on the VESC tool PC edition: make connection:
8. Then connect to the secondary ESC on the CAN bus:
9. Then reset the secondary ESC's APP settings.
On the right sidebar, click '<nowiki/>'''Read app configuration'''<nowiki/>', '<nowiki/>'''Read default app configuration'''<nowiki/>', ''''Write app configuration'''<nowiki/>' to restore default settings.
10. Then go back to main ESC, do setup input wizard:
11. Do ADC mapping:
In this step, push/rotate the throttle, triggle the mechanical brake or rotate the analog brake to let the VESC learn the throttle and brake input voltage, '''Apply then next.'''
'''If you don't have a mechanical brake or analog brake, set the mode to "Current Reverse Button" instead of "Current Reverse ADC2 Brake Button".'''
11. Then set the secondary ESC as slave to follow main ESC.
Finished, test the throttle and brake to check if two ESCs are running normally.
'''If you want reverse and curise function, go to set "APP to Use" to "ADC" only mode:'''
Two wheel drive only mode with one way throttle on VESC tool mobile[[Adapter V2 manual&veaction=edit&section=19|edit]][[Adapter V2 manual&action=edit&section=19|edit source]]
On VESC tool mobile, the principle is same, only the UI apearence is different, and we need a BlueTooth module to make wireless connection with phone. Below screenshots are based on VESC tool moble for ios.
Let's do parepares as discribled above, and step 1-6 in the chapter "'''Two wheel drive only mode with one way throttle on VESC tool PC edition'''".
Power on the Ubox V2 plug a BlueTooth module into the NRF socket.
Click the power button of Ubox V2 3 times, wait 1 seconds, Ubox V2 will swtich the NRF connection to ESCA, the bule LED will turn on at ESCA side.
Start the VESC tool mobile APP.
Two/one wheel drive switch-able[[Adapter V2 manual&veaction=edit&section=20|edit]][[Adapter V2 manual&action=edit&section=20|edit source]]
If you want a switch-able system, you need to separate two ESCS from CAN bus, let them working alone. And set each of the two ESCs one by one.
1.    Do the prepare steps.
2.    Set adapter to two/one wheel drive switch-able mode.
3.    After Ubox power on, and button LED solid, click the button 7 times, then wait 1 second, the internal CAN bus connection is off.
4.    Plug in an ADC cable from adapter's main socket to ESCA's socket.
5.    Plug in another ADC cable from adapter's second socket to ESCB's socket.
6.    Do setup input wizard setps as "'''Two wheel drive only mode with one way throttle'''" separately for each ESC.
When two ESCs are finished, to check if both ESCA and ESCB are working correctly, and to try to switch the two/one wheel drive mode, to check if the switching is working.
Two way (centered) throttle[[Adapter V2 manual&veaction=edit&section=21|edit]][[Adapter V2 manual&action=edit&section=21|edit source]]
Two way throttle setting is similar to above two modes, except we need to choose the '<nowiki/>'''Current No Reverse Brake Center'''<nowiki/>' mode in the APP Settings->General->General page, instead of ''''Current Reverse ADC2 Brake Button'''<nowiki/>'.
Before configure on VESC tool, set adapter to two way (centered) throttle mode first.
Concludes and explains[[Adapter V2 manual&veaction=edit&section=22|edit]][[Adapter V2 manual&action=edit&section=22|edit source]]
1.    The reverse function is mapped on to the RX pin of VESC's ADC & UART socket. And the cruise function onto the TX pin. So we suggested to '''use ADC only mode instead of ADC and UART mode'''. This is a link to illustrate the mapping of TX RX pins: <nowiki>https://vesc-project.com/node/600</nowiki>
2.    If you don't need the reverse and cruise function, you can set the 'APP to use' to 'ADC and UART'.
3.    There are many ADC control mode in the VESC, the most flexible mode is '''Current Reverse ADC2 Brake Button,''' it supports cruise, reverse, and ADC brake, if you want a button brake, you can let the brake input connect to a button with the other pin of the button connected to VDD (3.3V).
4.    For UBox's power button click function, please refer: [[The power button of Ubox|The power button of Ubox.]]
5.    On Ubox dual, the two/one wheel drive switching can also be achieved by Ubox's power button to turn on/off its internal CAN bus connection.
6.    For the ignite key and voltage meter of Ubox V2, please refer: [[The CAN-IN and IGNITE socket of Ubox V2|The CAN-IN and IGNITE socket of Ubox V2.]]
Caution and limits[[Adapter V2 manual&veaction=edit&section=23|edit]][[Adapter V2 manual&action=edit&section=23|edit source]]
1.    '''Use a battery to power the system instead of a AC adapter power source, because AC adapter can't handle the brake current, will damage the ESC or power source. And recommend to add a fuse in to the power line to deal with accidents.'''
2.    '''For two/one wheel drive switchable mode, when switch to one wheel mode, the ADC1 and ADC2 pins of secondary ESC are floating! This is the default circuit design of most VESC hardwares,''' '''a floating ADC input is easy to be interfered, cause the ESC out of control! Make pull down resistors on ADC pins to the GND, 20K - 30K is usually appropriate.''' Ubox V2 and Ubox single 100V have built in pulldown resistors, no need extra pulldown resistors.
3.    Since our solution is based on open source VESC, users should fully understand the risks of open source projects. This article only describes the possibility of this build method, and is not responsible for the damage and accidents caused by user themselves.

//Editing, will be finished soon.

The V3 adapter is designed to make wiring and configurating more conveniently and intuitively.

By placed LEDs for each port, input and output, it will be the most easy way to verify and diagnosis your wiring, Even the analog throttle input and output!

And by make two simple calibrations (throttle and optional analogy brake input), the configurations on the VESC can be simply import a app-config file we provided.

Also we changed all the out put MOSFETs to hi-side switch, this is more convenient to use co-ground lights in market.

Adapter V3.png

Size: 63 x 53 x 12.5 mm

This manual is based on Ubox V2 dual, for the other VESCs, the conceptions are the same.

Features

  1. Horn, head light, turn light, brake & rear light, and reverse light support.
  2. All FETs are hi-side PMOS, support co-ground lights.
  3. High, middle, low, 3 level throttle support.
  4. Motor reverse and cruise support.
  5. Buzzer to prompt turn and settings.
  6. Support both hall brake and mechanical brake input.
  7. Throttle current monitor, clear the VESC throttle ADC1 immediately when the throttle's '-' wire broken, ignores the pull-upped throttle input.
  8. Two/one wheel drive support.
  9. Convert 5V throttle and analog brake input signal to 3.3V range, no harm to VESC.

Wiring

[pictured needed]

  • Mechanical brake, light, horn, reverse and cruise are actually switches, we don't need to distinguish the two wires of each switch.
  • The turn left/right switch and throttle level switch, they usually has three wires, the neutral wire is the one which can be switched on/off to other wires, so if you are not sure the wire orders, use a multimeter to test them to find the neutral wire first, then know what the rest two wires are.
  • Usually, hand bar throttle or thumb throttle have three wires: black, red, green, corresponding to GND, 5V, throttle output.
  • Users can also use these type of throttles to make ADC(analog) brake, in Adapter V2, the ADC brake signal is transferred to VESC's ADC2 pin.
  • The second VESC ADC PORT is for two wheel drive config, if you have one wheel drive only, connect MAIN PORT to VESC.
  • Adapter need a 5V and 12V power source, the 5V is get from VESC ADC port, users need to connect a 12V power source to adapter's 12V socket, for Ubox V2 connect to its FAN socket.
  • The rear and brake light, usually comes with three wires in common ground connection mode, the two lights share one GND. Connect the positive(anode) wire of rear light to 12V, and brake light's to Brake light+, and their negative(cathode) wire to GND.
  • The other lights and horn are also high side switched, so connect the positive(anode) wire to the function pin, and the negative(cathode) wire to the pin to the 'G' pin.
  • For Ubox single 75V, the extra NRF port is not available, or for the other VESCs without NRF port (some vendor referred as second UART), if the cruise and reverse functions are not needed, the TX and RX pin from the 8 pin port can connect to VESC Bluetooth by pick out the wires from the cable. Or you can refer to this small kit : the single vesc UART port seperator:https://spintend.com/collections/diy-tools-and-accessory/products/single-vesc-uart-port-seperator

The throttle, brake , their switch and potentionmeters

Some ebike/escooters have 3 level throttles, VESC does not support 3 level.

Most throttle working on 5V, and output voltage up to 4.2V, VESC can only accept ADC input within 3.3V (3.44V for some hard ware version).

VESC supports analog brake (variable/propotional) input to its ADC2, common ebike/escooter only provide a electronic switch attached to mechanical brake.

The adapter V3 do these translating jobs, makes VESC a full funtional ebike/scooter controller.

The adapter V3 divide the 5V range throttle, remap it to 3 levels, send to VESC ADC1; Simulate an analog brake voltage to the VESC ADC2 when the mechanical brake switch is triggered; Co-work analog brake input with mechanical brake. This dividing, remapping, and simulating can be adjust to require your demands with these switch and potentiometers:
