From the project

Hardware design, BOM, gerbers, 3D files and pinout for Soldered-Inkplate-2 designed by Soldered Electronics.

The Inkplate 2 is an Arduino-compatible board that features a 2.13" three-color e-paper display. It is a plug-and-play device, programmable via USB port, and controlled by an ESP32 microcontroller. Moreover, it connects to the internet via WiFi or Bluetooth. Since it uses only 8uA in low-power mode, it can last for months on a single Li-ion battery charge. It's simple enough to be used by beginners, but it also offers plenty of features and a user-friendly platform for advanced users. Inkplate 2 has it all, packed on a small-factor board.
