## Description

### The ESP32-S3 dev board!

#### What is it?

A development / test board.

A small one, as small as you can get with sensible GPIO pins. Main board 30x32mm

#### Why not other boards?

This is a neat board and small. The wide voltage range, the WAGO power connector. The high power regulator for peripherals. It makes it a key starter board for any project.

The USB is connected to allow direct flashing and debug via USB port from ESP-IDF platform.

#### What makes it special?

Very small

An ESP32 with some oomph - dual processor, 4M flash 2M SPIRAM plus base RAM. Serious SoC.

All of the GPIOs available!

Small, and the power supply is a TI buck converter that is up to 2A at 3.3V to help supply peripherals you are connecting.

USB-C for power and debug/flash, or WAGO for DC from 5V to 17V

WS2812 LED on GPIO0 - does not stop the general use of GPIO0, but means you can use the LED if driven with WS2812 drivers.
