Product Description
ESP32-C3 SuperMini is an ultra-compact IoT development board built around the Espressif ESP32-C3 — a powerful 32-bit RISC-V single-core processor with onboard WiFi and Bluetooth 5.0 (LE). Measuring just 22.52×18mm, it’s one of the smallest ESP32-based boards available, making it the go-to choice for wearable electronics, miniature IoT nodes, and space-constrained wireless projects.
Despite its tiny footprint, the ESP32-C3 SuperMini packs serious capability — 160MHz processing speed, hardware encryption, an external antenna for stronger signal range, and rich I/O interfaces — all at an exceptionally low price point.
