Frequently Asked Questions

Q: Is the ESP32-C3 SuperMini board compatible with the Arduino IDE?

A: Yes! The ESP32-C3 SuperMini is fully compatible with the Arduino IDE. You can add ESP32 board support via the Arduino Board Manager, then upload sketches just as you would with any Arduino-compatible board. It also works with PlatformIO and other popular development environments.

Q: What is the difference between the soldered and unsoldered pin versions?

A: The soldered pins version comes with header pins already attached, so you can plug it directly into a breadboard or use jumper wires immediately. The unsoldered version ships without header pins, giving you the flexibility to solder custom connectors or integrate the board directly into your PCB design.

Q: Can I use this board for battery-powered or wearable IoT projects?

A: Absolutely. The ESP32-C3 SuperMini is specifically engineered for low-power applications. With a deep sleep current of approximately 43 µA and its ultra-compact 22.52 × 18 mm footprint, it is well-suited for wearable devices, remote sensors, and other battery-operated IoT projects where size and power efficiency are critical.

Q: How many boards can I order, and does the price cover multiple units?

A: This listing offers packs of 1 to 10 boards, making it a convenient option for individual makers, educators, and small development teams. Select your preferred quantity at checkout to stock up for multiple projects.
