Shield URL: Patch Shield v5.0
The patch shield is a cross between a patch panel/bay and a Wingshield. It's designed for times when you want to have remote sensors, or a control panel, or LEDs, or...practically anything where you want to avoid doing a lot of icky wiring!
The origins of this shield are unclear. It appears to originate at the site linked above. For kit information see:
Open Source: Yes, OSHW-compliant
License: CC BY-SA 2.5
License Note: As far as I can see the maker intends for this to be Open Source, but I can't find the source files themselves anywhere.
No pins are reserved by the shield: it simply breaks them all out to connectors.
