4.7inch 540x960 E-Ink Display with ESP32

The E-Ink display from DFRobot has 4.7 inches, 540 × 960 pixels and 16 grey levels and is controlled by an ESP32 with Wi-Fi and Bluetooth. Like every E-Ink display it keeps showing the image without power and is easy to read, which makes it suitable for displays that rarely change, such as price tags or shelf labels. Partial refresh is supported. A 3.7 V battery connects to the PH2.0 socket; in addition there is a connector for a touchscreen, buttons on the side and 7 inputs and outputs.

Note: Under the same number DFRobot now also supplies a version with ESP32-S3 (ESP32-S3-WROOM-1, 2 user buttons, 40-pin header following Raspberry Pi). The data here apply to the version with ESP32-WROVER-E; the printing and the module on the board show the version. The matching touchscreen has been discontinued at DFRobot.
