Best value for learning IoT
As a student, this board offers incredible value. It connects to my home network instantly and the Bluetooth Low Energy features work flawlessly with my phone app. Highly recommend for anyone starting with ESP32.

Great board, minor pin labeling issue
Performance is excellent and the C3 chip runs cool even under load. My only complaint is that the silkscreen pin labels are a bit small to read without a magnifier. Otherwise, a solid choice for industrial IoT sensors.

Compact powerhouse
Don't let the size fool you; this thing is powerful. I'm running a web server on it with no issues. The USB-C connector is sturdy and makes connection much easier than the old Micro-USB boards.

Solid hardware, needs external debugger for advanced use
The board works great for standard sketches. However, if you need JTAG debugging, remember this specific model doesn't have the header populated, so you'll need to solder wires or use a separate probe. Still a great buy.

Perfect size for wearable projects
The SuperMini form factor is exactly what I needed for my smartwatch prototype. It fits easily into small enclosures while still offering full Wi-Fi and BLE capabilities. Programming via the USB-C port was seamless with the Arduino IDE.

Reliable for home automation nodes
I have deployed six of these around my house for temperature monitoring. They have been running stable for three months without a single disconnect. The power consumption is also very low in deep sleep mode.
Q: Are the GPIO pins 5V tolerant?
A: No, the ESP32-C3 is a 3.3V logic device. Applying 5V to any GPIO pin may damage the microcontroller. Please use a logic level converter if interfacing with 5V sensors or modules.
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 5V or 3.3V pins. This board lacks an onboard battery charging circuit. You need an external TP4056 charger module or a dedicated power management shield.
Q: Does it support MicroPython out of the box?
A: The board comes with a basic bootloader. You will need to flash the MicroPython firmware yourself, which is a straightforward process using the esptool.py utility. It is fully supported.
Q: Is this board compatible with the standard Arduino ESP32 library?
A: Yes, this board is fully compatible with the Arduino IDE. You just need to select 'Xiao ESP32C3' or the generic 'ESP32C3 Dev Module' in the board manager after installing the ESP32 package by Espressif.
Q: What is the maximum current this board can supply to peripherals on the 3.3V pin?
A: The onboard LDO regulator can typically supply up to 500mA, but we recommend drawing no more than 300mA from the 3.3V pin to ensure stability, especially when Wi-Fi is transmitting.
