Just started shipping their (eyewateringly expensive) crowdsupply version https://www.crowdsupply.com/morpheans/sharpikeebo
Sources and Gerbers available so you could get a couple fabbed at JLPCB or fab of your choice fairly easily https://github.com/...
I'd be inclined to run it with an open hardware replacement for the Zero such as https://openkits.easyeda.com/...
Like this? 
Pretty cool, but I'd just chop off the bottom half and use anything else as an input device.
