http://www.farnell.com/datasheets/79209.pdf For related IC instructions, you can refer to the link above or search for HT82K629A in Lichuang Mall. There will also be related instructions. For convenience, I have screenshots for you to refer to. For convenience, I have not modified it. , if necessary, you can thicken the gnd and vcc lines. In order to avoid interference, you can make +; For reference, or draw one yourself. The original parts I use are all 0805 patches. For convenience, the interface is USB. If you need type-c, you can modify it yourself. You only need to connect a few pins and other shields. Type-c pins are generally relatively It is dense and requires a certain amount of soldering ability. The 2-pin crystal oscillator I chose is relatively large. If you want to change it to 4-pin, just change it yourself.
You can refer to the picture below for the pin link. If you have any questions, you can ask me. I can solve the simple ones, but I can't solve the difficult ones. ![)NAJK_DUR)JAN@AX1{[FFGQ.png]
