This kit includes a set of accelerator knobs and a brake handle; The variable-speed rotating handle is sturdy and durable, and uses a Hall device to non-contactly collect the rotation angle position. Input +5V, corresponding output voltage is 1V~4V according to the rotation angle; There is a switch inside the brake handle. When the brake handle is pressed, the switch is turned on, the red and black wires are connected, and the release switch is turned off. The variable speed handlebar and brake handle signal cables are 1 meter long and use sh1.0-3 interface; The physical interface and electrical interface of this kit have been optimized and are compatible with the pwm module (2.0A/2.0B) we sell on Amazon. They can be used directly together to achieve shifting and braking control, especially suitable for motorcycle types. The power wheels are upgraded. When this pedal is connected to pwm 2.0B, be sure to power on the pwm module again to ensure that the pwm module can recognize the pedal. (The pwm module only detects whether the transmission pedal is inserted every time it is powered on)
