Full GPIO breakout for ESP32-C3 Supermini Built-in 3.7V lithium battery support USB charging with status indicator LED Dual power outputs (3.3V / configurable 3.7V) Simplifies wiring for IoT and embedded projects
The Expansion Board for Supermini ESP32-C3 is a companion board designed to extend the functionality of the ESP32-C3 Supermini development module. It provides easier pin access and adds power management features for embedded and IoT projects. Additionally, it simplifies wiring during prototyping and testing.
The board exposes all GPIO pins of the ESP32-C3 Supermini in a more accessible layout. Moreover, it includes a built-in charging circuit for a 3.7V lithium battery. This allows users to power projects using rechargeable batteries while developing portable devices.
Furthermore, the expansion board supports USB charging with a clear charging status indicator. It also provides dual power outputs (VCC1 and VCC2), which usually output 3.3V by default. In addition, users can modify solder jumpers to switch output to 3.7V when needed.
The board is widely used in IoT prototyping, wearable electronics, and battery-powered ESP32 projects. Therefore, it helps developers build more stable and portable systems without extra wiring complexity. It focuses on improving power handling and GPIO accessibility rather than adding new computing features.
Expansion Board for Supermini ESP32-C3 delivers improved power control and full GPIO breakout support for easier ESP32-C3 development and battery-based projects.
