Some days ago we got some small PCAs for the cabling. Essentially small PCBs with a USB connector, a pushbutton to enable USB reprogramming, and vias for soldering the flat cable from the casing. After some soldering work we could finally put together one complete pair of shoes with an OpenShoe system in both shoes.
As you can see shrinking cable has been used around the small PCAs. The package is a little smaller than a normal USB connector. Mini USB connectors are used.
We have not yet put up any production files for the small PCAs since there were some small flaws in them which we had to correct manually. Hopefully this will come soon.
