ESP32-S3 SuperMini IoT Development Board, Wi-Fi and Bluetooth 5

The ESP32-S3 SuperMini is an ultra-compact IoT microcontroller board powered by the ESP32-S3FH4R2 chip with integrated 2.4GHz Wi-Fi and Bluetooth 5 (LE). Running at up to 160MHz with a built-in floating-point unit, it handles real-time data and wireless tasks efficiently. It is ideally suited for makers, students, and hobbyists developing space-conscious wireless and wearable projects.

Processing and wireless performance

Equipped with a 32-bit single-core processor running at up to 160MHz and a floating-point unit (FPU), the ESP32-S3 provides responsive computation for IoT applications. It features built-in 2.4GHz Wi-Fi conforming to IEEE 802.11 b/g/n standards alongside Bluetooth 5 (LE) dual-mode connectivity.

Compact design and versatile I/O

The ultra-small board features a single-sided surface-mount design with onboard reset and bootloader mode buttons. It offers 11 digital I/O pins with PWM support, 4 analog ADC pins, and serial communication support for UART, I2C, and SPI.

Low power and battery management

Optimised for battery-operated devices, the board draws just 43μA in deep sleep mode. It supports external power supplies from 3.3V to 6V connected directly to the rear B+ and B- pads, complete with built-in battery charging functionality.
