ESP8266-based LED Driver designed to work with WLED and cheap 12V barrel-jack power supplies for accent lighting around the home.
This driver was designed to allow network-enabled control of almost any 12V "dumb" strip around, from plain white to FCOB strips to RGBW.
My v1.0 worked perfectly, so I'm going to leave it as-is. The only upgrades I'd make at this point are:
- WLED announced that they're deprecating ESP8266 support right after I ordered v1.0, but for driving a single color the ESP8266 should be more than enough.
- There's some whine from the Power mosfet drivers, but it's barely noticable and not really worth addressing unless I was already doing a redesign.
See Releases for all the necessary files and information to make your own!
- Uses mini blade fuses for overcurrent protection and to protect against fire hazard from shorts on bad quality LED strips
- Board designed to handle up to and above maximum expected from most LED strips (8A)
- 4 channels to handle RGBW: or up to 4 single-color strips
- Terminal block for ease of use connecting strips and a 2.1mm jack allowing use of cheap 12V supplies you have lying around
- Capable of both programming and debug over SOICbite Connector.
- Includes status and power LEDs and board overvoltage protection
- See ABOUT.md for some information about design goals and the project.
| Output | ESP Pin |
|---|---|
| LED_R | GPIO 5 |
| LED_G | GPIO 13 |
| LED_B | GPIO 14 |
| LED_W | GPIO 12 |
| STATUS LED | GPIO 16 |
I also designed a 3D printable case, which can be found under case/. The screw terminals are still easily accessible, and there's a window on the bottom so you can see the board name and version without having to open it.
- The case uses M2x8mm screws to hold the two halves together, and is designed to be printed in PLA with 10% infill.
- Complete redesign from v0.2, with a focus on overall system design and ease of setup for the end user.

- My first 4 layer board! But some improvement still possible
