Solid performance
Using this in a custom robot controller. The Bluetooth connectivity is stable, and power consumption seems lower than previous generations. Would give 5 stars if it came with header pins pre-soldered, but that's a minor issue.

Good board, pins are tight
The board works perfectly with the Arduino IDE. My only minor complaint is that the pin headers are soldered very close together, so if you plan to use jumper wires directly, be careful not to short them. Otherwise, excellent product.

Ideal for learning embedded systems
As a student, this board is perfect. It's affordable, has plenty of documentation online, and the 4MB flash gives me enough room for complex sketches. Highly recommend for beginners.

Perfect size for compact projects
This Super Mini board is incredibly small yet packs all the features I need. The USB-C connection is a huge plus, and it was recognized immediately by my computer without needing extra drivers.

Fast shipping and reliable
Arrived the next day as promised. Flashing the firmware was instant. I'm using this for a home automation node, and the signal strength is surprisingly good for such a tiny antenna.

Great value for money
I bought this to replace an older ESP8266 project. The dual-band Wi-Fi and Bluetooth LE work flawlessly. Compilation times are fast, and the RISC-V architecture handles my sensor data logging easily.
Q: Is the USB cable included in the package?
A: Yes, the package includes one short USB-A to USB-C cable suitable for powering the board and uploading code.
Q: Does this board support MicroPython out of the box?
A: The board hardware is fully compatible with MicroPython. You will need to flash the MicroPython firmware onto the device first, which is a straightforward process using tools like esptool.
Q: What is the maximum current draw for the GPIO pins?
A: Each GPIO pin can source or sink up to 40mA. However, the total current drawn from all GPIOs combined should not exceed the chip's maximum rating. Please refer to the official ESP32-C3 datasheet for detailed electrical characteristics.
Q: Does this support OTA (Over-The-Air) updates?
A: Yes, the ESP32-C3 supports OTA updates. You can implement this feature using the Arduino IDE libraries or the native ESP-IDF framework to update your firmware wirelessly via Wi-Fi.
Q: Can I power this board with a 3.7V LiPo battery directly?
A: No, please do not connect a LiPo battery directly to the 5V or 3.3V pins. This board does not have a built-in charging circuit. You should use a separate regulator or a dedicated battery module to step down the voltage safely to 5V input.
