I am looking for specs to the ChipKit Uno32 connectors Specifically the "shield" interfacing connectors:

J2 - Shield Power Connector 1x8 J5 - Digital Signal Connector 2x8 J6 - Digital Signal Connector 2x8 J7 - Analog Signal Connector 2x6 J11 - I2C interface connector 1x2

I could just get pmod connectors, solder them, plug 'em in, but I want a neater look, one using real connectors to a cable that will last the test of time and environment. The board I need to interface to is already pre-made, and does not following the pinouts/size/etc. So, does anyone know of any premade cables or nice dressable connector that plugs into J2, then J5/J6, then J7, then finally one for J11?

If not, where do I find the connector specs showing pitch length, etc. Is there a "name" that is associated with these types of cables that would help my internet search looking for what "cables r us"'s of the world carry?

Thanks in advance, Bert

The connectors are 0.1" pitch "Board-to-Board" connectors. They are not intended for use with cables, but people do anyway for prototyping. I am not aware of any good permanent wire-based connectors for them.

Instead they are designed to be used with 0.1" pitch PCB headers to, as you noticed, mount a shield. Typically you would use some form of prototyping shield to provide the connectors you require in a good rugged way.

There are many manufacturers of the headers that are used on the Uno32, and there is, as far as I know, no real "name" for them except "PCB header". One well-known manufacturer is "Harwin" who have their "M20" range (one example:

The Uno32-style boards are really aimed prototyping, not finished-product usage. For that something more like the Fubarino SD or Fubarino Mini is a better choice since it allows you to solder wires directly to the board without needing any connectors.
