The ESP32S3SuperMini is an IoT mini development board based on the ESP32-S3 WiFi/Bluetooth dual-mode chip. The ESP32-S3 is a 32-bit CPU containing a FPU (Floating Point Unit) for 32-bit single-precision arithmetic with powerful computational capabilities. It has excellent RF performance and supports IEEE 802.11 b/g/n WiFi and Bluetooth 5 (LE) protocols. The board comes with an external antenna to enhance signal strength for wireless applications. It also features a small and compact form factor combined with a single-sided surface mount design. It is equipped with a rich set of interfaces, with 11 digital I/Os that can be used as PWM pins and 4 analogue I/Os that can be used as ADC pins, and it supports four serial interfaces, including UART, I2C and SPI.
There is also a small reset button and a bootloader mode button on the board. Translated with DeepL. com (free version)
