Q: What kind of car is suitable?

A: Sorry, due to the different internal parts of the vehicles, we cannot determine which model is suitable. We only apply the UART2 protocol controller.

Q: I don't know the agreement. How can I check it?

A: You can look for it from the appearance of the controller, the manual of the controller or the old display screen, and the seller of the controller or the old display screen.

Q: Can the UART protocol be used?

A: No, there are many protocols in UART, such as bafang, kds, etc. UART2 is just one of them

Q: May I ask if the speed limit can be lifted?

A: It depends on whether your car is limited by the controller or the display screen. If the controller limits the speed, there is no way to lift the speed limit. If the display screen limits the speed, the speed limit can be lifted

Q: Can I try out this product? If it doesn't suit me, can I return it?

A: No, no returns or exchanges for non-quality issues.

Q: What voltage range does your display screen support?

A: Our display supports 24V/36V/48V/60V.(The S810 only supports 36v.)

The default speed of our product is unlimited (100). If your controller has a speed limit, our display can only display the corresponding speed.

Questions & Answers

At this time, the controller not only cannot detect it, but also causes the controller to not work, resulting in communication failure between the instrument panel and the controller;
