Spin-Y manual V1
Spiny is a throttle for VESC and common e-scooter/bike.
Feature
- Maximum Hand grip, specially at full throttle.
- Bidirectional operation (forward accelerate, backward e-braking) .
- Remapped 0-3.3v signal, extend the hall range to get more interference immunity, and safe for VESC and similar controllers compared to common 5V throttles.
- 5v signal out put for All standard controllers like Minimotors/ Dualtron/ zero/ Vsett and others.
- Variable e-brake up on reverse scroll.
- Standard controllers use it mid to max as throttle only, can block with screw backward rotation!
- Button at the back can be used for external function (dedicated signal wire) .
Specification
| Working voltage | 3.3-5V, suggest 5V |
| Out put resistance on VESC/normal throttle, variable brake | 330 Ohm |
| ON resistance of Cruise button and E-brake | 22 Ohm |
| Off load current 5V supply, no driving out | 20 mA |
| Normal throttle out put range | 0--4.2V, adjustable |
| VESC throttle out put range | 0--3.3V, bidirectional，1.65V at center position |
| Color | Function | Explaination |
|---|---|---|
| Black | - GND | Negative power supply, and low side of rear button and E-brake switch |
| Red | + 3.3/5V | Positive power supply, can accept 3.3-5V, recommend 5V |
| White | VESC Throttle | VESC ADC1, centered (bidirectional) |
| Green | Normal Throttle | One way signal for normal ESC, NOT for VESC |
| Yellow | E-Brake ON/OFF | ON/OFF to GND for ESC brake |
| Blue | E-Brake variable | Variable brake for ESC support it |
| Brown | Rear button | Button to GND for external DIY devices, such as cruise, lights/horn etc. |
Calibration
Spiny has three LEDs, under the wheel, to indicate the calibration state: green, yellow, red. For easy to observe the LED state, do calibration at a darker place will helps.
All the calibration are enter by hold the rear button then power on it.
Wheel travel calibration
Spiny can be more accurate after calibrate the wheel travel.
- Hold the rear button, and pull backward (to right) the wheel, then power on spiny.
- Wait 3 seconds for the yellow LED start blinking, then release rear button.
- When yellow LED blinking, push and pull the wheel to its full travel for several times, then release the wheel, to wait until green LED on.
- Finished, to check if the function is normal, if not, go to step 1 and try again.
Start point adjust for normal throttle
Start point is for normal ESC, usually they have start voltage at 0.7V and end voltage 4.2V.
You can observe the ESC and motor to find the right start point.
- Hold the rear button, and the wheel at the start position you wanted, then power on spiny.
- Wait 3 seconds for the green LED start blinking, still hold the wheel at its position, then only release the button.
- Wait the green LED solid, then release the wheel.
- Finished, to check if the start point is meet your requirement, if not, go to step 1 and try again.
- Tips, if you did not hold the wheel when adjusting, the start point is set to zero, this is helpful for clear the former adjusting.
End point adjust for normal throttle
End point is for normal ESC, the ESC's acceptation of the end voltage is varying, adjusting the end point can match their requirements.
You can use a multimeter to measure the voltage of the wire (green) to get an accurate end point voltage.
- Hold the rear button, and the wheel at the end position you wanted, then power on spiny.
- Wait 3 seconds for the red LED start blinking, still hold the wheel at its position, then only release the button.
- Wait the red LED solid, then release the wheel.
- Finished, to check if the start point is meet your requirement, if not, go to step 1 and try again.
- Tips, if you hold the wheel at it's maximum position when adjusting, the end point is set to 4.2V, this is helpful for clear the former adjusting.
The rear button and E-brake
When the rear button is pressed, it's wire(brown) will connect to the GND, there is a 22 ohm resistor serial in the circuit, to prevent short. When button released, the connection to the GND will be open.
When the pull the wheel backward (to right), it's wire(yellow) will connect to the GND, there is a 22 ohm resistor serial in the circuit, to prevent short. When wheel released or pushed forward, the connection to the GND will be open.
