Dled esp32-controller

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 repository contains code to use the ESP32's RMT peripheral to drive digital LEDs.

The code dedicated to this board is not yet built.
