Perfect for compact IoT projects
The built-in OLED screen is a game changer for debugging without needing a serial monitor. The ceramic antenna provides stable Wi-Fi connectivity in my smart home setup.

Ideal for student workshops
Bought ten of these for our robotics club. The small form factor fits perfectly into custom 3D printed cases, and the screen allows students to see output immediately.

Good signal strength
The ceramic antenna performs better than expected for such a small board. Only wish it had a battery connector header pre-soldered, but easy enough to add.

Great board, slight learning curve
Hardware is solid and the USB-C connection is convenient. Took me a little while to get the display library working with MicroPython, but documentation helped.

Reliable and feature-rich
Been running a temperature monitoring station on this for two weeks straight with no crashes. The low power consumption modes work exactly as described in the datasheet.

Excellent value for RISC-V development
Switched from ESP8266 projects to this C3 model. The performance boost is noticeable, and having Bluetooth LE alongside Wi-Fi opens up many new possibilities.
Q: Does this support external PSRAM?
A: This specific model does not include external PSRAM. It relies on the internal SRAM of the ESP32-C3 chip, which is sufficient for most standard IoT applications.
Q: Can I power this board with a 5V USB charger?
A: Absolutely. The board features an onboard voltage regulator that accepts 5V input via the USB Type-C port and converts it to the required 3.3V for the ESP32-C3 chip.
Q: What is the resolution of the 0.42-inch OLED screen?
A: The integrated OLED display has a resolution of 72x40 pixels, which is sufficient for displaying sensor data, status icons, and simple menus.
Q: Is the ceramic antenna removable or replaceable?
A: No, the ceramic antenna is soldered directly onto the PCB and is not designed to be removed or replaced. It is optimized for the board's specific layout.
Q: Does this board support Arduino IDE out of the box?
A: Yes, you can use the Arduino IDE. You will need to install the ESP32 board manager package and select the 'Xiao ESP32C3' or generic 'ESP32C3 Dev Module' depending on your specific driver setup.
