Please help if you know the answer.  I am a geek but not when it comes to Ebikes.  I am looking to upgrade my display with a Bafang hub motor 750 display. The requirement says it has to be a UART protocol. I have a 2020 Rad rover 5. Does anyone know if Rad uses the Bafang that supports UART? Has anyone done the screen upgrade?

Thanks
