Frequently Asked Questions
Q: Is the ESP32-C3 SuperMini compatible with the Arduino IDE?
A: Yes! The ESP32-C3 SuperMini development board is fully compatible with the Arduino IDE. Simply add the Espressif ESP32 board package to your IDE, select the appropriate ESP32-C3 board profile, and you can start uploading sketches via USB just like any other Arduino-compatible board.
Q: What is the difference between the Soldered Pins and Unsoldered Pins versions?
A: The Soldered Pins version comes with header pins already attached, making it immediately ready for use on a breadboard or in a prototype circuit. The Unsoldered Pins version ships with loose headers so you can solder them yourself — ideal if you need a lower profile or a custom pin configuration for your specific project.
Q: How low is the power consumption in deep sleep mode?
A: The ESP32-C3 SuperMini draws approximately 43 µA in deep sleep mode, making it extremely well-suited for battery-powered IoT devices and wireless wearable applications where extended battery life is a priority.
Q: Does the board have built-in security features?
A: Absolutely. The ESP32-C3 chip includes hardware-accelerated AES-128/256 encryption, SHA hashing, RSA, HMAC, digital signature support, and secure boot functionality — all at the silicon level — ensuring robust security for your IoT applications without sacrificing performance.
