8. User Tips
- Compatibility is Key: This C961 display is ONLY applicable to Bafang Mid/Hub Drive Motor Kits and specifically uses the BF-UART communication protocol. If your motor is not Bafang brand, or if your Bafang motor kit uses a different communication protocol (e.g., 5S-UART or CAN protocol with triangular connectors), this display will NOT be compatible. Always verify your motor's brand and communication protocol before purchase.
- The BF-UART protocol is typically identified by a 5-pin circular female connector. The 5S-UART protocol often uses a male connector, and the CAN protocol uses triangular connectors.
- For optimal performance and longevity, avoid exposing the display to direct sunlight for extended periods when not in use.
