The ESP32-C3 Super Mini Development Module (4MB) is a microscopic IoT development board based on the ESP32-C3, an efficient RISC-V single-core processor at 160 MHz.

It features built-in 2.4 GHz Wi-Fi and Bluetooth 5.0 (BLE), 4 MB flash memory, as well as full support for UART, SPI, I2C, ADC, PWM, and GPIO pins.

Its compatibility with Arduino IDE and ESP-IDF makes it ideal for programming and experimenting with IoT projects, smart home devices, sensors, and automations.

Thanks to the very small size of the board, it can be easily integrated into portable or space-restricted applications, offering stable wireless communication and low power consumption.
