Where's an inexpensive place to get a couple of small 2.85" x 3.5" double sided PC boards made?
I've designed a small interface board that will optically isolate the step/dir/enable signals before they become differential RS422 for the STMBL AC Servo Drive. Along with 5V for the MESA 7i92H and a couple of optically isolated transistors to reset the HP_UHU DC Servo drives. The board also can be jumpered instead to provide RS422 for step/dir but Open Collector drive for Enable and receiving and isolating Open Collector Fault from the Bergerda AC Servo Drives. So a whole bunch of features in one small DIN rail mountable board. Thanks John
