@rtr12 posted:Just added this one to the OGR projects list. Let me know if you see anything I should add or change (link in sig below). Another fine project for the forum members! And thanks again for all you do for us around here, much appreciated!
Looks good to me. 
@Jim Sandman posted:GunRunnerJohn - Does this sensor board also work for Proto 3, or just Proto 2? It seems to imply Proto 2 for sure with the mention of the LocoSound.
True PS/3 tach boards are a totally different design both electrically and physically, they're not compatible with this board. However, the PS32 Stacker board actually uses the PS/2 style sensor board and would work with this board.
@Dave Zucal posted:John, the QRE1113 contains an LED. Is the resistor needed to limit current to the LED for LocoSound, and if so, why doesn't the LED need current protection for the PS2 application?
The PS/2 boards include current limiting for the LED in the QRE1113, the LocoSound boards obviously do not, hence the resistor for those. Note that for LocoSound replacements, you may not need the resistor on the board as it's frequently included in the wiring harness.
