Ubox V2 100V manual
Ubox V2 75V is a member of our V2 family, the other members are Ubox V2 100V, adapter V2, Uni1 remote V2.
Features
- All the 12V,5V, VCC external ports are recoverable fused, all the HALL, TX&RX are serialized with a resistor, ADC1, ADC2, ADC3 are pulled down with a 22K resistor.
- Independent external VCC, the MCU's VCC isolated, and guarded by a TVS.
- Ignite key and meter supported, fused, for e-scooter/e-bike application.
- Three 12V control ports: front light, horn, and brake light! these ports are separated 2pin sockets.
- Cooling fan socket with 12V power source.
- CAN bus insert power on supported, easy for 4WD configuration.
- External NRF(Bluetooth) socket, to replace the former internal BT module, independent from main UART ports, also A/B switchable.
- VCC is 3.44V, 100% compatible with VESC original FW, no more 3.3V VS 3.44V issue.
- External antenna for internal 2.4 GHz receiver.
- Support both momentary and latching power buttons.

Unique functions
With Uni1 remote (Uremote), the head light, brake light, and horn are controllable.
Brake light control supports external PPM signal input to ESCB.
When without Uremote, several function still can be set by simply click the button.
Limits and cautions
- 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.
- This product is for DIY purpose, so we only offer a very limited warranty.
FAQ
Q:Does the switch using GND 5V?
A:No, the switch button is the trigger signal of the internal power on circuit. After it is turned on, 12V, 5V and 3.3V will be available.
Q: How can I build a 4wd with Ubox V2?
A:Ubox V2 is specially designed for 4wd.
The Ubox V2 has two CAN sockets: in and out, the 5V pin of CAN IN socket, is just for trigger on this Ubox's own power source, the 5v pin of CAN OUT socket, can provide 5V power to other devices. This will take the advantage of 12V power source of each Ubox. Please refer: How to setup a 4WD with Ubox V2, and a special article for 2/4WD switch-able configuration.
Q: What if I plugged CAN cable into CAN OUT which comes from the master ESC?
A: The slave Ubox you plugged-in CAN cable can still work, but its own 12V will not work, all of its system working power will from your CAN cable input.
Q: Does Uni1 remote works with Ubox V2?
A: Yes, it works with V2, and can control the brake light
Q: Can I make a 4WD with V1 and V2?
A: Yes, V2 can be CAN cable trigger on, so let the V2 serve as secondary ESC, we can do 4WD.
- Power button plug into V1.
- CAN cable connect from V1 to the CAN-in of V2.
Q: When I configuring the 4WD, the two Ubox’s behaver is confusing, what’s happening?
A: When combine the U-remote and two Ubox，the receiver in Ubox will report data to remote, when two Ubox are reporting to remote, they will confusing. This can be solved by disable one of the two Ubox’s receiver function:
- Power off remote and Ubox.
- Plug power button into the Ubox you want to disable
- Click button to power on this Ubox.
- When button’s greed LED solid, continuously click the button 9 times, then wait 1S, the LED will turn off, then light again. Disable is done.
Q: How to check the receiver is disabled?
A: In normal, when power on, button’s LED will blink 3S to search the remote signal. If it is no blink at all, the receiver function is disabled.
Q: How to re-enable receiver function?
A: Repeat above steps, in step 4, click button 8 times, instead of 9 times.
Q: Can the brake light works in ADC mode?
A: No, The brake light is controled by internal reciever, when this receiver received the brake throttle from Uremote, it will switchs on the light.
For ADC mode, receiver don't know the ADC throttle, so it keeps the light off.
We have redesign the ADC adapter to support the E-scooter/E-bike's brake light, turn light, front light, and horn, the adapter V2.
