Love the USB-C
Finally a mini board with USB-C! No more hunting for micro USB cables. The size is incredibly small which fits perfectly in my wearable project.

Easy to flash
Driver installation was smooth on Windows 11. Bootloader works reliably and the reset button is easy to access for entering flash mode.

Perfect for IoT
Wi-Fi connection is stable and the Bluetooth LE works well for my sensor network. Highly recommend for home automation prototypes.

Tiny but powerful
Great for compact projects where space is limited. The USB-C connection makes programming very convenient compared to older micro USB boards.

Good value
Works with Arduino IDE out of the box after adding the board manager URL. Only minor issue was pinout labeling could be clearer on the silkscreen.
Q: Can I power it with 3.3V directly on the VIN pin?
A: We recommend powering via the USB-C port. If using GPIO, ensure voltage levels match 3.3V logic to prevent damage to the regulator.
Q: Does it have an external antenna connector?
A: No, this SuperMini version uses the onboard PCB antenna. For external antenna needs, please check our Pro versions with U.FL connectors.
Q: Does this board support MicroPython?
A: Yes, the ESP32-C3 SuperMini is fully compatible with MicroPython firmware. You can flash it using esptool.py.
Q: Is it compatible with existing ESP32 code?
A: Most code is compatible, but note that the C3 uses a RISC-V architecture instead of Xtensa. Some specific libraries may need adjustments.
Q: What is the maximum current output per GPIO pin?
A: Each GPIO pin can source or sink up to 40mA. However, the total current for all ports should not exceed specified limits to avoid damage.
