Overview
Dimmer is an open-source printed circuit board by flaviut, from the flaviut/led-dimmer repository on GitHub. It is a 2-layer board of 25 × 46.3 mm with 47 parts on 37 nets, routed with 242 tracks and 61 vias.
It is built around the ESP-12F, RY8310 and AMS1117-3.3, with the HY1503C1 and WNM2030 among its other parts. Its parts include 16 resistors, 10 capacitors, 10 transistors, 3 ICs and 3 connectors. It belongs with the home automation and IoT and lEDs and displays boards and the ESP8266 boards of this library.

README
README.mdIoT RGBWW strip dimmer
Designed for use with ESPHome, this project is a compact & powerful dimmer for all LED strips. The primary goal was low cost, in the most compact package possible. For scale, the picture above was taken on a 1 inch grid.
This is intended as a substitute for the poorly-designed Magic Home LED strip controllers.
Note: the yellow wire in the photo does not work as a capacitive touch sensor, that was a failed experiment.
Features
- Up to 5 lighting channels
- Support for voltages between 5V and 24V
- Up to 4A per channel. Outputs can be paralleled.
- Reasonable efficiency: approx. 200mW standby power draw.
- Low cost, PCB is about $6/ea manufactured at qty 10, or about $4.30/ea at qty 30.

Questions
How big is the Dimmer PCB?
It measures 25 × 46.3 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Dimmer use?
47 parts, built around the ESP-12F, RY8310, AMS1117-3.3 and HY1503C1. 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 Dimmer KiCad files?
From the flaviut/led-dimmer repository on GitHub, at the commit this page was made from: the board is dimmer.kicad_pcb and its schematic dimmer.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Dimmer design in my own project?
Its repository states no licence, so its author keeps all rights: ask flaviut before reusing the design.
