ESP32-C3 Supermini Board

The MCDODO ESP32-C3 Supermini is a compact IoT development board supplied as a three-pack. It targets hobbyists and engineers who need multiple Wi-Fi and Bluetooth nodes for prototyping or small-scale deployments.

Best for multi-node prototypes

Suits developers building mesh networks, sensor arrays or classroom kits where identical boards simplify code reuse. Not suited for projects that require on-board USB-to-serial circuitry, higher GPIO counts, or integrated battery charging circuits.

Three boards per pack

The quantity of 32 boards is not offered; this pack contains exactly three units, making it the deciding factor for buyers who need a small, ready-to-use batch without sourcing singles.
