Best bang for your buck
You cannot beat the specs at this price point. 4MB flash and dual wireless protocols in such a tiny package make it my go-to choice for all new embedded designs.

Seamless Bluetooth LE integration
I bought this specifically for a BLE beacon project. The Bluetooth 5 support works flawlessly with low power consumption. Highly recommend for battery-powered applications.

Great value, minor pin labeling issue
Performance is excellent for the price. The RISC-V core handles my sensor data logging without issues. Only downside is the silk screen pin labels are a bit small to read without a magnifier.

Perfect compact board for IoT projects
The SuperMini form factor is incredible. It fits easily into small enclosures where standard ESP32 boards won't go. Wi-Fi connection was stable right out of the box using Arduino IDE.

Solid for prototyping industrial sensors
We used these for rapid prototyping of wireless temperature nodes. They are reliable and the USB-C port is much more durable than the micro-USB on older boards.

Easy to get started
As a beginner, I was worried about setting up the environment. The board was recognized immediately by my computer, and uploading the blink example took less than 5 minutes.
Q: Can I power this board with a 3.7V LiPo battery directly?
A: No, this specific SuperMini model does not have an onboard battery charging circuit or raw input pin for direct LiPo connection. You must use a separate battery management module and feed regulated 5V or 3.3V.
Q: Is this board compatible with the Arduino IDE?
A: Yes, this ESP32-C3 board is fully compatible with the Arduino IDE. You simply need to install the ESP32 board manager package and select 'Xiao ESP32C3' or the specific C3 variant from the board list.
Q: What is the maximum current this board can supply to peripherals?
A: The 3.3V pin can typically supply up to 500mA depending on the USB source, but for stability, we recommend drawing no more than 300mA for external sensors and modules.
Q: Are there headers pre-soldered on the board?
A: This unit is sold as a bare board without pre-soldered headers to maintain its ultra-compact profile. You will need to solder your own pin headers or use pogo pins for connection.
Q: Does it support MicroPython?
A: Absolutely. The ESP32-C3 chip supports MicroPython. You can flash the latest MicroPython firmware using esptool.py and start coding in Python immediately.
