Perf++ is a similar design to Ben Wang's Perf+ 2 that he successfully funded through Crowd Supply. Hackaday did a story on it compared to other current perf board concepts -
Hackaday link. Our version is similar, but we have open sourced the footprints and plan to integrate them into shields, capes, etc.
Perf Footprint Design
Each perf footprint is made of a central 1.1mm through-hole with a D shaped ring. The flat side aligns with a solder bridgeable pad on either side that connects either to horizontal or vertical trace lines. This allows for conditional connections in either direction and the traces can be cut to isolate multiple connections on the same trace. Using this grid system, the number of jumpers is none or minimal.
Software
Perfy is semi-compatible in designing layouts on perf+ like systems.
Status
The intial shield works with the standard Arduino Uno. We will be improving the design and creating more on request/demand. We will experiment with shields, capes, hats, etc., depending on the success of the perf footprint and the usefulness of the Arduino shield.
We are still debating how best to implement the footprint around double pin rows that are more common to other board ecosystems.
The Arduino shield is selling on Tindie now, we may crowdfund on a later revision to lower the cost.
