From the project

ESP32-C3 based ePaper Devboard

Introducing the GuluESP32-C3ePaper Devboard: a cutting-edge development board powered by the ESP32-C3. This board features a modular power system, equipped with the EggLDO1000 by default for efficient performance. Designed to support a wide range of ePaper displays from WaveShare and Good Display that require the 0.47 Ohm resistor.

MCU: ESP32-C3-WROOM-02-H4 Power supply: EggLDO1000 * Connectivity: SPI, UART/USB, 24-pin FPC ePaper connection
