Great value, minor pin labeling issue
Excellent performance for the price. The RISC-V architecture runs smoothly. Only downside is the pin labels are very small and hard to read without a magnifier, but the functionality is top-notch.

Solid board for robotics control
Using this to control a small rover. The PWM outputs are precise. I deducted one star because the header pins were not pre-soldered, which required extra work, but that's expected at this price point.

USB-C is a game changer
Finally, a dev board with USB-C! No more fiddling with micro-USB cables. Flashing speed is fast, and the board stays cool even during heavy processing tasks.

Best ESP32-C3 board I've tried
I have tested several brands of ESP32-C3 boards, and this SuperMini version offers the best balance of size, power, and connectivity. Documentation online is plentiful too.

Perfect for compact IoT projects
The SuperMini form factor is incredible. It fits easily into small enclosures where standard boards wouldn't fit. Wi-Fi connection was stable right out of the box using Arduino IDE.

Bluetooth LE works flawlessly
I bought this specifically for a BLE sensor project. Pairing was instant and the range is surprisingly good for such a tiny board. Highly recommended for beginners and pros alike.
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 combined should not exceed the limits specified in the Espressif datasheet to avoid damaging the chip.
Q: Does it support MicroPython?
A: Absolutely! The ESP32-C3 chip supports MicroPython. You can flash the latest firmware using esptool.py and start coding in Python immediately.
Q: Are the headers included in the package?
A: This specific SuperMini listing usually ships without pre-soldered headers to keep the profile low. You will receive the board and may need to solder your own pin headers based on your project requirements.
Q: Can I power this board with a 3.7V LiPo battery directly?
A: No, you should not connect a LiPo battery directly to the 3.3V pin. This board expects 5V input via the VIN or USB-C port, which is then regulated down. Use a proper battery management system or feed 5V to the VIN pin.
Q: Is this board compatible with the Arduino IDE?
A: Yes, this board is fully compatible with the Arduino IDE. You just need to install the ESP32 board manager package and select the 'Xiao ESP32C3' or generic 'ESP32C3 Dev Module' depending on your specific setup.
