From the project

A WS2811 LED driver board compatible with MGP signal decoders.

A WS2811 LED driver board compatible with MGP signal decoders.

This LED driver board provides 8 LEDs via two 2x3p 1.27 mm pitch connectors, intended for up to two German light switching signals.

This board can be connected via three methods:

1. RJ45 cabling as used by signal mount drivers and described in the adapter board README. 2. Regular three-pin headers or servo connectors via J2 and J5. 3. Soldered wires via J3 and J6.
