①--Capacitive touch screen circuit

②--Resistance touch screen circuit

③--Disp resistance

④--P2 interface (compatible with atomic RGB interface)

⑤--P3 interface (compatible with wildfire RGB interface)

1. Switch touch screen

If you choose to connect the capacitive touch screen, please weld the capacitor touch screen circuit;

Select the connection resistance touch screen, please weld the resistance touch screen circuit;

If you often need to switch the touch screen, after welding other circuits, only switch the drain

resistance in the dotted line box;

2. Precautions for disp resistance welding

When connecting the wildfire development board for use, the disp resistance must be removed, otherwise

the screen will not display after the development board is reset;

When connecting atomic development board, f407 minimum system board or esp32 development board, disp

resistance must be welded, otherwise the screen will not be displayed.

3. P2 and P3 interface pins are described as follows:
