The Next Generation of IoT: Compact, Efficient, and Powerful The ESP32-C3 SuperMini Development Board represents a significant leap forward in the ESP32 family. Built around the high-performance RISC-V 32-bit single-core processor, this board is designed for low-power IoT applications that require both Wi-Fi and Bluetooth 5.0 capabilities. Despite its incredibly small "SuperMini" footprint, it packs enough punch to handle smart home devices, wearables, and complex sensor nodes with ease.
Advanced Connectivity with Bluetooth 5.0 LE Connectivity is the core of the ESP32-C3. It supports standard 2.4GHz Wi-Fi and features Bluetooth 5.0 Low Energy (LE), which offers better range and faster speeds compared to older Bluetooth versions. This makes it a perfect choice for battery-powered projects where power efficiency and stable wireless communication are critical.
Developer-Friendly and Breadboard Ready At Robogears, we know that speed of development matters. This board features a modern USB Type-C port for both power and programming, eliminating the frustration of old micro-USB cables. It is fully compatible with the Arduino IDE, ESP-IDF, and MicroPython, allowing you to use your existing code and libraries. Its narrow design ensures that when plugged into a breadboard, you still have plenty of access to the surrounding tie-points for your components.
