2.7 Inch E-paper Display Module
Low power, wide view angle, can display 2 colors (black and white)
This product is a 2.7-inch e-ink screen expansion module, based on the Raspberry Pi 40PIN interface design and suitable for Raspberry Pi series motherboards. We provide C and Python version demo codes for Raspberry Pi, and reserve the SPI control interface for easy access to Arduino, STM32 and other main control boards. We also provide Arduino, STM32, ESP32 version demo codes, which can realize picture display, English and digital character display, and point, line, rectangle, circle drawing.
Features
- 264 x 176 pixels
- Onboard Voltage Translator, which can be compatible with 3.3V and 5V MCUs
- The board is equipped with two buttons and two LEDs, making it convenient for users to expand their applications.
- Based on Raspberry Pi 40PIN GPIO header design, applicable to Raspberry Pi series motherboard
- Based on Raspberry Pi Pico header design, applicable to Raspberry Pi Pico motherboard
- SPI communication interface is reserved to facilitate connect to Arduino/STM32 and other control boards
- Open source demo codes available for Raspberry Pi, Raspberry Pi Pico, Arduino, STM32, ESP32 development boards
