Connecting the Screen
To connect the e-Paper display to a Raspberry Pi, connect each pin on the display to the corresponding GPIO pin on the Raspberry Pi as shown in the table below:
| e-Paper Connector | Raspberry Pi Pin (Board) |
|---|---|
| VCC | 3.3V (Pin 1) |
| GND | GND (Pins 6, 9, 14, 20, 25, 30, 34, or 39) |
| DIN | GPIO 10 (MOSI, Pin 19) |
| CLK | GPIO 11 (SCLK, Pin 23) |
| CS | GPIO 8 (CE0, Pin 24) |
| DC | GPIO 25 (Pin 22) |
| RST | GPIO 17 (Pin 11) |
| BUSY | GPIO 24 (Pin 18) |
For reference, you can find a detailed pin layout of the Raspberry Pi GPIO pins on the Pinout.xyz website.
Depending on the model of the e-Paper screen, you may also be able to connect the display directly as a HAT. Refer to the supported displays guide for more details.
