# ESP32 controller for digital LEDs

Efficiency, hardware control for digital LEDs and Wi-Fi communications - these are just some of the caracteristics of this controller.

It is designed to control digital LEDS like:

- WS2812, WS2812B, ... (*aka* NeoPixel) and derivatives like SK6812

- APA102 (*aka* DotStar) and derivatives like SK9822

**Status:** *this is work in progress !*

## Features

- using the ESP32's RMT peripheral, the controller is able to drive two strips of digital LEDs like: WS2812, WS2812B, WS2812C, WS2812S, WS2813, WS2815, WS2812D, etc.

- using the ESP32's HSPI peripheral, the controller is able to drive a strip of digital LEDs like APA102

- two *real* logic level shifter circuits

- the power supply for LEDs is controlled using a Power MOSFET

- I2C and two general-purpose extension headers

- high efficiency synchronous buck converter

- supply voltage supervisor

## Software

My [esp32_digitalLEDs](https://github.com/CalinRadoni/esp32_digitalLEDs) repository contains code to use the ESP32's RMT peripheral to drive digital LEDs.

The code dedicated to this board is not yet built.

## Development Environment

Operating system is [Debian](https://www.debian.org/)

Tools:

- [KiCad EDA](https://www.kicad.org/)

- [Visual Studio Code](https://code.visualstudio.com/)

- [Espressif IoT Development Framework](https://github.com/espressif/esp-idf)

- [Git](https://git-scm.com/)

- [GIMP](https://www.gimp.org/)

- [Inkscape](https://inkscape.org/en/)

## Versions

### Version 1
