Great value but needs careful handling
Excellent performance for the price. The only downside is that the pins are quite close together, so you need a steady hand or a breakout board for prototyping. Otherwise, it's a fantastic chip for low-power applications.

Perfect compact board for IoT projects
This SuperMini board is incredibly small yet powerful. The RISC-V architecture works flawlessly with the latest Arduino IDE and ESP-IDF. Wi-Fi connection is stable and the USB-C port makes programming very convenient.

Ideal for learning embedded systems
Bought this for my university project. Documentation is plentiful online, and the community support for ESP32-C3 is growing fast. Bluetooth LE pairing was straightforward to implement.

Tiny powerhouse
I am amazed by how much functionality is packed into such a small form factor. The build quality is good, and the antenna performance is surprisingly strong for its size.

Solid board with minor pinout quirks
Performance is top-notch. Just be aware that some GPIO pins have specific boot strapping requirements. Once configured correctly, it runs my sensor network without any drops.

Replaced my old ESP8266 boards
The upgrade from ESP8266 is noticeable. Faster processing, better power management, and native USB support eliminate the need for external converters. Highly recommended for Home Assistant integrations.
Q: Is this board compatible with the Arduino IDE?
A: Yes, the ESP32-C3 SuperMini is fully compatible with the Arduino IDE. You simply need to install the ESP32 board package via the Board Manager and select the 'Xiao ESP32C3' or generic 'ESP32C3 Dev Module' option.
Q: Does the Bluetooth support classic Bluetooth or only BLE?
A: The ESP32-C3 supports Bluetooth 5 Low Energy (BLE) only. It does not support Classic Bluetooth, which is different from some older ESP32 models.
Q: Does it support MicroPython?
A: Absolutely. You can flash MicroPython firmware onto the ESP32-C3. It is well-supported and allows for rapid development using Python syntax.
Q: What is the maximum current output per GPIO pin?
A: Each GPIO pin can source or sink up to 40mA. However, the total current for all ports combined should not exceed the limits specified in the Espressif datasheet to avoid damaging the chip.
Q: Can I power this board with a 3.7V LiPo battery directly?
A: No, this board does not have a built-in battery charging circuit. You should use a regulated 3.3V supply or connect a battery through an external LDO regulator or dedicated battery management module.
