Identifying the UART system

This controller is specifically designed for a UART system. The corresponding display can be identified, among other things, by the round 5-pin connector. The controller is also marked with the letter "U".

Important for ordering

Pay close attention to the system voltage: this controller works exclusively with a 43V system. Also check whether your e-bike uses the UART protocol. A 36V Bafang M400 controller or a controller for a different communication protocol is not automatically interchangeable.

Therefore, before purchasing, check the model number of your current controller, the system voltage, the motor type, and the connections.
