The ESP32-C3 SuperMini is one of the smallest Wi-Fi and Bluetooth boards you can buy. Its tiny size also makes wiring several components awkward. This expansion board fixes that. Plug the SuperMini in and each GPIO is broken out to its own clearly labelled header. That gives you plenty of room to connect sensors, displays, relays and servos without crowding a breadboard.
It turns the SuperMini into a neat, reliable base for prototypes, STEM lessons and permanent IoT installs. When the project is finished, you can pull the board out and reuse it.
Key Features
- Made for the ESP32-C3 SuperMini. The board plugs straight into the socket.
- All GPIO pins broken out. Every usable pin is easy to reach.
- Clearly labelled pins. Silkscreen labels help you avoid wiring mistakes.
- No soldering needed. Use jumper wires for quick connections.
- Breadboard-friendly. It also works on a breadboard.
- Removable module. Swap or reuse your SuperMini anytime.
- Quality PCB. It’s sturdy and durable for repeated use.
Specifications

How to Use
- Line up the ESP32-C3 SuperMini with the socket. Match the USB-C end to the marking on the board.
- Press the SuperMini gently into place.
- Connect your sensors and modules to the labelled GPIO, 3.3V and GND pins.
- Program the SuperMini over its USB-C port in the Arduino IDE (choose ESP32C3 Dev Module), MicroPython or ESP-IDF.
Tip: The ESP32-C3 GPIO pins work at 3.3V. Use a level shifter for 5V-only sensors and modules.
