Adapter-CMRI8-RJ45
CMRI Breakout8 Adapter RJ45 to 0.100, 3.5mm and 0.156 Molex
CMRI boards have traditionally used Molex KK 0.156 pitch I/O pins, which required crimping matching connectors onto layout wiring. This adapter board converts them into RJ-45 style used by common network cables. Crimping to RH45 connectors is (IMO at least) much simpler than the alternative. Another of these boards can be used at the other end of the 8-conductor cable, but this time it can be populated with a 0.1” or 3.5mm pitch screw terminal and mounted to the benchwork near where it’s signals are used.
