I’ve finished with the V2 light board layout and will be sending off to get some prototype boards made next week. Once all is done and documented, the files necessary to make the boards will be made available to anyone who wants to make their own. I will also sell them here on densha-bahn.com for those who just want some without the hassle.
The board is versatile as it allows a assortment of components to be used, including rectifier bridge, voltage regulator, LEDs, capacitors, and resistors that fit your needs. You can also easily trim the board to the length you need it. Once built up, you can run it on DC, DCC track power, or DCC decoder output. If using a DCC decoder to drive it, you can leave the rectifier bridge off if you want and it has special solder pads for that purpose as well.
