Hardware Connection

Working with Pi4B/3B+/3B/3A+

1. Use a 15PIN FPC cable to connect the DSI interface of the display screen to the DSI interface of the Raspberry Pi board. 2. Install the Raspberry Pi on the display board with the back facing down, and connect the 5V power supply and I2C communication through the 4PIN. The final connection is shown below:

Working with Pi5/CM4/CM3+/CM3

1. Use the "DSI-Cable-12cm" cable to connect the display's DSI interface to the 22-pin DSI1 interface on the Raspberry Pi board.
2. Use the "PH2.0 4PIN connection cable" to connect the display screen's 4-pin header to the 5V and GND pins on the Raspberry Pi board. (By default, it uses the I2C0 of the DSI interface. If using the I2C1 mode, you will need to additionally connect the SDA and SCL pins.)
