ESP32-C3 SuperMini Expansion Board
The ESP32-C3 SuperMini Expansion Board is a dedicated companion board designed to enhance the functionality and usability of the compact ESP32-C3 SuperMini development board. This expansion board brings out all 10 GPIO pins for easy connection to sensors, modules, and other peripherals, making prototyping and development more convenient.
One of its standout features is onboard support for a 3.7V lithium battery (PH2.0 interface), including charging capability via USB. A green LED indicates active charging and turns off when the battery is fully charged.
To provide flexibility in powering your projects, the board includes dual voltage outputs (VCC1 and VCC2). By default, both lines supply 3.3V. However, users can configure them to output 3.7V by modifying onboard solder jumpers—simply remove the default 0Ω resistor and bridge the pads with solder to reroute the voltage.
This expansion board is ideal for battery-powered IoT projects, wearables, and low-power applications using the ESP32-C3 SuperMini.
