Perfect compact board for IoT projects
The SuperMini form factor is exactly what I needed for my wearable project. The USB-C connection makes programming a breeze, and the RISC-V architecture performs surprisingly well. Highly recommended for beginners and pros alike.

Solid performance, gets warm under load
Runs my MQTT client without issues. Note that it does get slightly warm when transmitting Wi-Fi data continuously, but nothing concerning. The build quality feels premium despite the low cost.

Best board for learning embedded systems
I bought this for my university course. It connects instantly to the Arduino IDE and the Bluetooth Low Energy examples run right out of the box. The price point is unbeatable for the features provided.

Bought ten for our workshop
Equipped our entire lab with these. Students love the USB-C port because we don't need to stock different cables anymore. Reliable connectivity and very robust against accidental shorts.

Tiny but mighty
Using this to control some smart lights. The size allows it to fit inside small junction boxes easily. Power consumption seems lower than the older ESP8266 boards I used previously.

Great value, minor documentation gaps
Hardware is solid and the Wi-Fi range is decent for such a small board. Had to dig into the official ESP docs to map out all the GPIO pins specifically for this layout, but once set up, it works flawlessly.
Q: Does this board support 5GHz Wi-Fi networks?
A: No, the ESP32-C3 chip only supports 2.4GHz Wi-Fi networks (802.11 b/g/n). It does not support 5GHz bands.
Q: Is the CH340 driver required for Windows?
A: This board typically uses a built-in USB-to-UART bridge within the ESP32-C3 or an external CP210x/CH34x depending on the specific batch. Most modern Windows 10/11 systems will auto-install drivers, but if not, you may need the CP210x or CH340 driver from the manufacturer's website.
Q: Does it come with headers pre-soldered?
A: No, to keep the profile ultra-low and versatile, this board is shipped without pre-soldered headers. You will need to solder your own male or female headers depending on your project requirements.
Q: Can I power this board directly with a 3.7V LiPo battery?
A: Yes, you can connect a 3.7V LiPo battery to the 3.3V pin if regulated, or use the VIN pin which accepts a wider range (typically up to 5V), but please check the specific schematic for onboard regulator limits before connecting batteries directly to VIN.
Q: How many ADC pins are available?
A: The ESP32-C3 has multiple ADC channels, but on this specific SuperMini breakout, usually 2 to 3 ADC-capable GPIOs are broken out and accessible for analog reading. Please refer to the pinout diagram included in the package.
