Perfect for IoT Projects

The SuperMini form factor is exactly what I needed for my smart home sensors. Wi-Fi connection is stable and the USB-C port makes programming easy.

Learning Curve

Board works fine but the documentation could be clearer for beginners. Had to search forums to get the drivers installed correctly.

Arduino Compatible

Uploaded sketches easily using the Arduino IDE. The ESP32-C3 core is well supported and runs my code without issues.

Good Value Board

Works well for the price. The pins are a bit tight to solder if you are not used to SMD components, but performance is solid.

Low Power Consumption

Deep sleep mode is very efficient. I am getting weeks of battery life on my remote monitoring project. Highly recommend.

5 FAQ

Q: Is ESP-IDF supported?

A: Yes, this board is officially supported by the ESP-IDF framework from Espressif.

Q: Does this work with the Arduino IDE?

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

Q: Are the GPIO pins 5V tolerant?

A: No, the GPIO pins operate at 3.3V logic levels. Applying 5V directly may damage the board.

Q: What is the maximum current output?

A: We recommend drawing no more than 500mA from the 5V pin to ensure stable operation.

Q: Can I connect an external antenna?

A: No, this SuperMini version uses a fixed onboard PCB antenna and does not have a connector for external antennas.
