This universal driver board can be used to drive various Waveshare SPI interface e-Paper raw displays from a Raspberry Pi. The driver can also be used with other development boards, such as Arduino, using the included cable. See the Wiki for hardware connections for various platforms. The board includes slide switches to allow compatibility with different display types and also 3 or 4-pin SPI selection.
