Overview

The ESP32-S3 Super Mini puts Espressif’s most powerful general-purpose ESP32 chip on a board about 18 x 23 mm. The ESP32-S3 has two Xtensa LX7 cores at up to 240 MHz, 2.4 GHz Wi-Fi and Bluetooth 5 LE, plus vector instructions that speed up small AI and signal-processing workloads.

USB-C connects straight to the chip’s own USB peripheral, so there is no separate USB-serial converter: plug it in and program it from the Arduino IDE, ESP-IDF or MicroPython. The castellated edge pads let you solder it flat onto a carrier board, or fit the supplied headers for a breadboard.

Key Features
