RJ45 Wiring Harness for Microchip's ICD2

About: As a programmer and a maker, I love building things. I share my creations to inspire other folks to get out there and build.

Microchip's ICD2 provides a 6 wire pigtail to program and debug PICs. This instructable shows you the pin-out for connecting this pigtail to an RJ45 female connector.

    Its a very good idea but the connector on the ICD2 unit is actually a RJ12 (same as US telephone connector but all 6 conductors) An easy (and cheap) solution for connectors with the ICD2 unit is to make a 10 Pin IDC cable (5pins x2 rows) with the RJ12 on the other side. IDC headers fit on Strip-boards better than RJ12 sockets. If you recycle a lot of old components like me then you find it harder to get RJ12 sockets with all 6 pins at times. where as ICD headers are a plenty, you can pull them off almost anything.

    my IDC ICD2 cable pinout is as follows if your interested:
    (as if looking at the header on a target board)
    Pin Function
    [1 2] = PGC
    [3 4] = PGD
    [5 6] = GND
    [7 8] = Vcc
    [9 10] = Vpp/MCLR

    All my boards have this connector added.
