SPECIFICATIONS

ESP32S3SuperMini is an IoT mini development board based on the Espressif ESP32-S3 WiFi/ Bluetooth dual-mode chip. The ESP32-S3 is a 32-bit RISC-V CPU that contains the FPU (floating point unit), which can perform 32-bit single-precision operations and has powerful computing power. It has excellent RF performance and supports IEEE 802.11b /g/n WiFi and Bluetooth 5 (LE) protocols. The board comes with an external antenna to enhance signal strength for wireless applications. It also has a small and delicate form factor combined with a single-sided surface mount design. It is equipped with a wealth of interfaces, with 11 digital I/ OS that can be used as PWM pins and 4 analog I/ OS that can be used as ADC pins. It supports four serial interfaces: UART, I2C and SPI. The board also has a small reset button and a boot loader mode button.

Based on the above features, ESP32S3SuperMini is positioned as a high-performance, low-power and cost-effective iot mini development board suitable for low-power iot applications and wireless wearable applications.
