ESP32-C3 Super Mini Development Board — RISC-V, WiFi + BLE 5.0, Ultra-Compact

ESP32-C3 Super Mini Development Board — RISC-V, WiFi + BLE 5.0

The ESP32-C3 Super Mini is one of the smallest ESP32-based development boards available — a RISC-V single-core processor with WiFi and Bluetooth 5.0 LE in an ultra-compact footprint. The RISC-V architecture and ultra-low power consumption make it ideal for battery-powered IoT nodes, wearables, and space-constrained embedded applications. Compatible with Arduino IDE, MicroPython, and ESP-IDF.
