The CAN-IN and IGNITE socket of Ubox V2
[pitcure needed]
Ubox V2 has two new sockets in its panel: CAN-IN and Ignite:
CAN-IN
Ubox V1 was not considered for 4WD when we designing it, and it has a independent power on control mechanism. So when people want to build a 4WD with Ubox V1, it is not so convenient. we didn't consider it carefully at that time, I'm sorry.
Ubox V2 makes 4WD easy, by separating CAN-IN and CAN-OUT socket, with one CAN bus cable, 4WD will work. [picture needed]
Why we need to separate the IN and OUT? Because, Ubox supports momentary type button, the EN signal of the 12V power source is maintained by a MCU, so it can not self turn off when the 5V from the CAN cable is disappeared. By discriminate the CAN-IN 5V, the MCU can give up the EN control, let the CAN-IN 5V to take control of the EN, the CAN-IN 5V is only used for trig on the Ubox.
The CAN-OUT is a plain CAN socket, it out puts the 5V source.
Ignite
The Ignite socket is hided away[picture needed], because it has a battery voltage in it, this is often too high to be safe, so we hided it. Don not plug the power button in it.
The ignite socket is for the E-bike/E-scooter, to comply with their ignite key and voltage meter.
The ignite key returns the battery voltage back to ESC, ESC then powers on.
The voltage meter measures the the battery voltage relative to GND.
So Ubox provide GND, VBATT and IGNITE, three pins. Short the VBATT and IGNITE, Ubox will power on, release them, Ubox will power off immediately.
Connect a voltage meter with GND and VABTT, the meter will indicates the battery voltage. Do not short the VBATT and GND, it will blow the fuse, yes we fused VBATT pin.
The VABTT pin is not designed for providing buck current, it is not suggested to draw more than 1A current from it.
