ESP-RGB-LED

An embedded software project for controlling LED strips using an ESP8266 microcontroller
The project consists of three main folders: software, pcb, and housing

Software

A MicroPython module that can control an LED strip using the GPIO pins of an ESP8266 microcontroller
Input is received via wifi, written in a custom Python-like language which is parsed and executed onboard

PCB

A KiCAD project to design a PCB to power the ESP8266 and LED strip

Housing

A SOLIDWORKS project to design a 3D-printable housing for the PCB

Questions

How big is the ESP RGB LED PCB?

It measures 61 × 78.7 mm and has 2 copper layers, 1.6 mm thick.

What parts does the ESP RGB LED use?

10 parts, built around the IRLB8721PBF. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.

Where can I download the ESP RGB LED KiCad files?

From the Sean-AP/ESP-RGB-LED repository on GitHub, at the commit this page was made from: the board is pcb/ESP_RGB_LED.kicad_pcb and its schematic pcb/ESP_RGB_LED.kicad_sch. PCBKit opens the board in the browser, with nothing to install.

Can I use the ESP RGB LED design in my own project?

Its repository states no licence, so its author keeps all rights: ask Sean-AP before reusing the design.
