The MiLight gateway is a simple PCB to be used with the open-source milight gateway software by Chris Mullins.
Long time ago I’ve bought some of these MiLight RGB LED bulbs to control them with a raspberry pi and the openmilight project (see link at bottom).
That did not work very well so I was looking for a better solution – and found it right there:

In addition to this software project I created this PCB with minimal components, as I wanted to install it as permanent solution.
This is the very first PCB I created using KiCad after migrating from Cadsoft(now Autodesk) Eagle.
DIY kits to build your own minified standalone MiLight Gateway will be available in my shop soon!
Part list:
- ESP12E/ESP12S
- nRF24L01+ module
- AMS1117-3.3V
- SMD Mini-USB port or 2x male pin headers
- 2x 10µF 0805 capacitor
- 2x4pin female pin header
- optional: 1x5pin male/female pin header
Assembly Instructions
- Solder the ESP12S module
You can use some double-sided tape to hold it in place while soldering. - Solder SMD components
These are only an AMS1117 power regulator and two capacitors. The Micro-USB connector can also be added at this step. - Mount pin headers
The 2×4 female pin headers are used to connect the nRF2401 which controls the MiLight bulbs.
The 1×5 and 1×2 pin headers are optional and serve for power supply and/or programming the ESP8266. - Attach the nRF2401 and power it up
Use a 5V voltage source or an USB port.
On first boot it will create an insecure wifi access point called “ESP-xxxxxx”.
Connect and navigate to http://192.168.1.4. Now follow the setup wizard.

Shared project on OSHPark: 
Are these available pre built with software already flashed please ? Ship to UK ?
Sorry, it is not available yet.
But you can build your own using the supplied open-source schematics and PCB layout.
Me too waiting for update of this project since I’m very interested in
Hi Elenio,
The PCB available as an development kit – preflashed with the NodeMCU firmware, but it’not become a finished device, so you still have to program it with Chris’s firmware and add an nRF2401 module to build this project.
