Description
Product Description:
The ESP32-S3 SuperMini Development Board is a compact, high-performance, and low-power IoT board designed for next-generation connected devices. Built around the ESP32-S3 dual-mode Wi-Fi and Bluetooth 5 (LE) chip, this board delivers excellent wireless performance, rich interface support, and advanced security features in an ultra-small form factor.
Engineered for IoT, wearable, and embedded applications, the ESP32-S3 SuperMini integrates a 32-bit processor with floating-point support, 4MB Flash, and 400KB RAM. It supports multiple Wi-Fi modes (Station, SoftAP, and Mixed), features ultra-low power consumption with deep sleep capability (~43μA), and includes an external antenna for enhanced wireless range and signal stability.
Despite its tiny footprint—smaller than a thumb—it offers a wide range of digital and analog I/O, making it a powerful choice for compact IoT, robotics, and automation projects.
