Module with E-Ink (e-Paper) display with a diagonal of 2.9"and a resolution of 296x128 px with WiFi communication. It uses the popular ESP32-S2 chip, thanks to which it can be programmed, for example, by Arduino IDE. There are 4 RGB LEDs on the board, four user buttons and two 3-pin STEMMA and buzzer connectors. The module also has a built-in 3-axis accelerometer to detect the orientation of the display. It can be powered by a USB type C connector or by a battery and is equipped with a charging circuit. E-Paper displays are characterized by high contrast of the displayed image and consume power only when the displayed content is changed. On the product page, support is available in the form of examples and documentation.
