Hardware Connection
1. Connect the GPIO interface
Raspberry Pi leads out 40 GPIO pins, while the screen leads out 26 pins. When connecting, pay attention to the corresponding pins and Raspberry Pi pins.
2. Connect the HDMI connector to the HDMI port of the screen and the Pi.
3. Turn the Backlight on the back of the LCD to "ON".
Note: Raspberry Pi Zero / Zero 2 W needs an additional HDMI cable for connection.
