Great value but pins are small

Works well for my home automation setup. Just be careful when soldering headers as the pins are quite close together.

Good board, steep learning curve

Hardware is solid but finding specific libraries for some sensors took some time. Good for intermediate users.

Perfect for small IoT projects

This board is incredibly small yet powerful. Connected to Wi-Fi instantly and the USB-C connection is very convenient.

5 FAQ

Q: What is the maximum input voltage?

A: The board operates at 3.3V logic. You can power it via 5V USB-C or the 5V pin, but do not exceed 5V on GPIO pins.

Q: Are the headers pre-soldered?

A: No, this SuperMini version comes without headers to save space. You will need to solder them yourself if required.

Q: Does it support classic Bluetooth?

A: No, the ESP32-C3 only supports Bluetooth Low Energy (BLE 5.0), not classic Bluetooth.

Q: Is this compatible with the Arduino IDE?

A: Yes, this board is fully compatible with the Arduino IDE. You need to install the ESP32 board package.

Q: Can I power external sensors from this board?

A: Yes, there is a 3.3V output pin, but please ensure the total current draw does not exceed the regulator's limit.
