The ESP32-C3 Super Mini Development Board is a compact wireless microcontroller board built around the ESP32-C3FN4 chip. It is designed for developers and learners for WiFi and Bluetooth capability in the smallest possible board size without giving up essential peripheral access.
Unlike larger ESP32 variants, this low-cost microcontroller board uses a single-core 32-bit processor instead of the dual-core architecture according esp32 devkit v4 module. at 160 MHz and is more than capable of handling sensor reading, wireless communication, and protocol processing for most embedded applications. The board design keeps the footprint minimal while retaining GPIO access for I2C, SPI, UART, and ADC connections.
The esp32 c3 mini module carries 4MB of flash memory and 400KB of SRAM, which is adequate for running web servers, BLE peripherals, and sensor data pipelines. The esp32 wifi module functionality supports 2.4 GHz 802.11 b/g/n WiFi, while the Bluetooth 5.0 LE radio handles short-range device pairing and data exchange.
Powering and programming is done through Super Mini Development Board, which connects to the internal USB-to-serial bridge. The wide voltage input range of 3.3V to 6V gives flexibility for different power source choices in field-deployed projects.
Available through StemVolt, this board is a practical choice for microcontroller learners who need a low-footprint wireless board for compact project builds.
