I have now selected a domestic development board to complete this function. This development board is called Orange Pi, and it uses Allwinner_H3 chip. I wanted to use raspberry pi, but it is too expensive, so I gave it up. Although the Orange Pie is cheap, it does not seem to have many resources,and there are not many online tutorials. I have no experience in the field of mpu, so I think I need a lot of time to learn how to use it.
