Good for prototyping
Works great out of the box with Arduino IDE. The only reason for 4 stars is that the OLED brightness could be slightly higher for outdoor use, but indoors it is perfectly clear.

Compact and powerful
Love the form factor. The ceramic antenna performs surprisingly well compared to external whip antennas I've used on older boards. Battery life seems decent when using deep sleep modes.

Easy to get started
As someone new to ESP32, this board was very forgiving. The community examples for the OLED screen worked immediately. Fast shipping and well-packaged too.

Excellent value for money
I bought five of these for a university project. The RISC-V architecture is interesting to work with, and the built-in screen makes debugging output very convenient without needing a serial monitor constantly.

Great board, minor documentation gaps
Hardware is solid and the USB-C port is a nice touch. Had to dig around a bit to find the specific pinout for the OLED display in the official docs, but once configured, it works flawlessly with MicroPython.

Perfect for compact IoT projects
The integrated OLED screen saves so much wiring hassle. The ESP32-C3 is fast, and the ceramic antenna provides a stable connection in my smart home setup. Highly recommended for beginners and pros alike.
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 5V and GND pins if the board has a voltage regulator, or directly to the 3.3V pin if you bypass regulation, but we recommend using the USB-C port or a dedicated battery management module for safety and stability.
Q: What library should I use for the OLED display in Arduino?
A: We recommend using the 'U8g2' library by oliver. It supports a wide range of displays including the 0.42-inch OLED found on this board. Ensure you select the correct constructor for your specific interface (usually I2C).
Q: Is the USB-C port used only for power or also for data?
A: The USB-C port serves both purposes. It provides 5V power to the board and acts as the UART interface for flashing firmware and serial monitoring.
Q: Does this come with a protective case?
A: No, this package includes only the development board. Protective cases are sold separately or can be 3D printed using dimensions available in our product documentation.
Q: Does this board support 5GHz Wi-Fi networks?
A: No, the ESP32-C3 chip on this board only supports 2.4 GHz Wi-Fi networks. It does not have 5GHz capability.
