The Open LED Project aims to offer open source RGB LEDs for various popular buttons. These will be worked on over time, but there are no guarantees that all buttons will get an RGB LED board. Please do not ask for specific buttons to be made.
These boards are designed to be hand soldered, not assembled. An assembly version may be made in the future. Due to the fact that these are double sided assembly costs will be high if those plans are released.
These boards use standard WS2812B (5050) RGB LEDs.
Notes:
- These boards are only compatible with Sanwa 30mm buttons, not 24mm buttons.
- These boards are only compatible with clear Sanwa 30mm buttons
- These boards are only compatible with genuine Sanwa 30mm buttons, they may not fit on clone buttons
- There may be manufacturing variances from JLC between batches due to the small overall size and tight tolerances. It is recommended to test fit before assembling.
These boards are designed to snap onto the bottom of a clear Sanwa 30mm button. They feature two WS2812B (5050) RGB LEDs as well as a data in and data out 3pin 2.00mm connector.
This connector is pinned in the standard manner used on the RP2040 Advanced Breakout Board and other RP2040 based devices that I have made.
There is no capacitor for the LEDs but I do not believe it is needed on something small like this given the newer LEDs.
This board is designed to be hand-soldered. I have increased the size of the pads for the WS2812B RGB LEDs so that they are easier to hand solder.
2 x WS2812B RGB LED
2 x JST 3pin 2.00mm vertical connector
These parts can be sourced from AliExpress or most part sellers.
All of the boards so far have been ordered though JLCPCB. Due to the small size it is recommended to order these in batches.
