Click to zoom
Quick Overview
The DIYables ESP32-C3 SuperMini Development Board is an ultra-compact WiFi and Bluetooth LE IoT module built on the ESP32-C3 chip featuring a single-core 32-bit RISC-V processor running up to 160 MHz. Designed for energy-efficient applications, this board is optimized for wearables, portable devices, and battery-powered smart systems. It comes fully presoldered with header pins already attached, making it immediately compatible with breadboards and jumper wires — no soldering required out of the box.
The board provides 11 digital GPIO pins (all PWM capable) and 4 analog ADC inputs for flexible sensor and peripheral expansion. Communication interfaces include UART, I2C, and SPI, and the modern USB-C port handles both power and programming. The super mini form factor with castellated edges allows use on breadboards or surface mounting in production designs. Integrated 2.4 GHz WiFi (802.11 b/g/n) and Bluetooth 5.0 LE enable reliable wireless connectivity for IoT applications.
This 2-pack set is ideal for prototyping multiple projects, educational use, and DIY electronics development. Fully compatible with Arduino IDE (with ESP32 board package), ESP-IDF, and MicroPython. Perfect for wearable IoT devices, BLE beacons, smart sensors, WiFi data loggers, home automation, and any application requiring a compact, low-power wireless module.
