Universal SPI E-Ink Display Driver Board
Suitable for Raspberry Pi series mainboards, Arduino, STM32, ESP32 and more.
Can drive various sizes of E-Ink screens.
This product is a universal SPI E-Ink display bare-board driver, suitable for Raspberry Pi series mainboards, Arduino, STM32, ESP32 and more. It comes equipped with an E-Ink screen adapter board and a flexible flat cable (FPC) for driving various sizes of E-Ink screens. We provide C and Python sample code for Raspberry Pi, as well as ESP32, Arduino and STM32 sample code. These sample codes enable drawing points, lines, rectangles, circles, displaying English alphanumeric characters, and images on the E-Ink screen.
Product Features
- SPI interface with relatively few pin requirements.
- Raspberry Pi 40-pin GPIO interface for direct connection to Raspberry Pi series mainboards.
- Onboard level-shifting chip for compatibility with both 3.3V and 5V microcontroller interfaces.
- Two LEDs and two buttons for user DIY applications.
- Open-source example programs available for Raspberry Pi, Arduino, and STM32 development boards.
