Ideal for Home Assistant nodes
Using these as remote sensors for my Home Assistant setup. The Bluetooth LE support allows for easy presence detection, and the Wi-Fi range covers my entire garage. Very stable uptime over the last month.

Reliable and fast shipping
Board arrived well-packaged. Tested all GPIO pins and the ADC readings are consistent. The built-in antenna performs surprisingly well for such a small device. No issues with driver installation on Windows 11.

Perfect for compact IoT projects
This SuperMini board is incredibly small yet powerful. The USB-C connection makes flashing firmware a breeze without needing external adapters. Wi-Fi and BLE connectivity worked flawlessly out of the box with the Arduino IDE.

Good for student projects
Bought ten of these for our university robotics club. They are robust enough to handle student errors and the low power consumption is great for battery-operated robots. Would give 5 stars if it came with header pins pre-soldered.

Best ESP32-C3 board I've used
Switched from the older ESP8266 boards and the difference in speed and stability is night and day. The form factor fits perfectly into my custom 3D printed enclosures. Highly recommended for beginners and pros alike.

Great value, minor pin labeling issue
The performance is excellent for the price point. My only complaint is that the pinout silkscreen is a bit tiny to read without a magnifier. Otherwise, the RISC-V architecture handles my sensor data logging perfectly.
Q: What is the maximum current this board can supply on the 3.3V pin?
A: The onboard LDO regulator can typically supply up to 500mA, but we recommend drawing no more than 300mA from the 3.3V pin to ensure stability.
Q: Are the headers included or do I need to solder them myself?
A: The board is shipped without headers soldered to keep the profile low. You will need to solder your own male or female headers depending on your project requirements.
Q: Is the antenna external or internal?
A: This model features an onboard PCB antenna. There is no connector for an external antenna on this specific SuperMini version.
Q: Does this board support MicroPython?
A: Yes, the ESP32-C3 SuperMini fully supports MicroPython. You can flash the latest firmware using esptool.py or the web installer.
Q: Can I power this board via the VIN pin instead of USB?
A: Yes, you can power the board via the VIN pin with an input voltage range of 3.3V to 5.5V. However, using the USB-C port is recommended for programming.
