Quick Overview
The DIYables ESP32-S3 Super Mini is an ultra-compact development board powered by the ESP32-S3FH4R2 chip, featuring built-in WiFi 802.11b/g/n and Bluetooth 5.0. At just 23.2mm × 18.2mm, it delivers the full wireless capability of the ESP32-S3 in one of the smallest available form factors, making it compatible with Arduino IDE and MicroPython for flexible development.
Header pins come pre-soldered, so the board plugs directly into a breadboard or connects to modules without any additional soldering. The ESP32-S3FH4R2 integrates 4MB flash and 2MB PSRAM, providing ample memory for embedded applications, wireless communication, and sensor data handling.
Ideal for space-constrained IoT builds, wearable electronics, wireless sensing nodes, and portable embedded projects where a compact yet powerful microcontroller is required.
