Description
2 layer board of 2.39x3.75 inches (60.66x95.25 mm).
isolated rs485/DMX splitter
not tested yet and really hoping that the first run here still works as I forgot the bypass caps requested by the data sheet. Thus improvement is welcome, but probably not bad for a first ever board. uses optoisolators and dc-dc converters to galvanicly and optically isolate 4 output buses from one input bus and each other.
uses MAX488 trancievers, 6n137 optos, and RI-0505S DC-DC converters by recom power.
