800x480 7.5inch 3-Color E-Ink Display Raspberry Pi HAT

This Waveshare E-Ink / e-paper display as a HAT has 7.5 inches, 800 × 480 pixels and an integrated controller that communicates via SPI. It displays the three colours red, black and white. Thanks to its extremely low power consumption it is suitable for battery-powered applications. Such displays are also used as price tags in retail, where they run for several years on one battery. The large panel is connected via a flat cable and the supplied e-Paper Driver HAT. According to Waveshare a full image update takes 26 s, 16 s in fast mode, so the display is not intended for applications that update every second.

Recommended Accessories:

• ESP32 Universal Raw e-Paper Driver Board WiFi Bluetooth

Features:

• Level converter on the board, therefore compatible with 3.3 V and 5 V microcontrollers
• The image remains visible without power supply
• Power is basically only needed for refreshing
• Viewing angle over 170°, easy to read even in sunlight
• SPI interface for Raspberry Pi, Arduino, ESP8266 or ESP32
• Example code from Waveshare for Arduino, STM32 and Raspberry Pi
• For the 40-pin GPIO header of the Raspberry Pi, for example 2B, 3B, 3B+, Zero, Zero W
• On the Driver HAT, the Display Config switch is set to B for this panel and Interface Config to 0 for 4-line SPI (as printed on the board)
• According to Waveshare, the ESP32 driver board also supports this panel, connected there via the flat cable of the panel

Application Examples:

• Price tags and labels
• Battery-powered displays for measured values and weather data
• Status displays that change rarely
