Hi Onion gang,
I've noticed that most of the docks have schematics on github at:
https://github.com/OnionIoT/Onion-Hardware/tree/master/Schematics
Notably absent: Breadboard dock. While it might seem like a trivial dock, having a schematic would reduce some confusion, e.g. whether the pin marked "3.3V" can be used as a VIN in lieu of a USB power input.
Please upload that schematic for the good of all Onionkind.
Thanks!
