This board is intended to simply CMRI wiring. This board has pads at 0.156 spacing for a (female) 8 position Molex connector on the 0.156 side on one side and an RJ45 style 8 pin phone/data jack on the other. Additional pads are provided on the Molex side for 0.100 or 3.5mm screw terminals which can be used in place of the Molex connector, providing a handy breakout for RJ45 cables.
The board was designed by John Plocher.
This allows you to extend anything with 8 wires on pre-terminated CAT5 cables.
