Interface Introduction

Power Supply and Touch Communication

In the default I2C0 mode, the DSI ribbon cable carries the display and touch signals, and no separate SDA1 or SCL1 connection is required.

The screen has relatively high power consumption, and powering it through the DSI ribbon cable alone is insufficient; you must additionally connect a 5 V power supply. Choose any one of the following power supply methods:

Power Supply Method	Connection Requirements	Notes
Spring pogo pins	The Raspberry Pi is secured to the back of the screen, and the pogo pins contact the 5V and GND of the GPIO	Installing additional standoffs may leave the pogo pins suspended; in this case, power can be supplied via the 4PIN or Type-C
4PIN Interface	Connect the 5V and GND of the mainboard to the corresponding 5V and GND of the screen	Wire according to the PCB markings, not by wire color
Type-C Interface	Connect a 5 V power supply to the screen's Type-C interface	Power supply only; does not transmit touch signals

Switching to I2C1 Touch Communication

1. After powering off, switch the DIP position of the "touch interface selection switch" in the figure above to I2C1.
2. Using the pogo pins or 4PIN, connect SDA1 and SCL1 to the I2C1 pins of the Raspberry Pi GPIO respectively. When using pogo pins, ensure proper contact.
3. Add ,i2c1 to the end of the screen's dtoverlay line in config.txt, save, and reboot.

The power supply method is the same as above, and the DSI ribbon cable still carries the display signal. When using Type-C power, you must still connect SDA1 and SCL1 via the pogo pins or 4PIN.
