Parker Dillmann of Longhorn Engineer writes to inform us that:
I just finished V1.1 of the Propeller Development Stick. Link to all the info here.
The stick is a miniature Propeller dev board which can plug directly into your computer’s USB port and was designed with goals of minimal cost and size.
You can check out the schmatic, PCB files and BOM at Parker’s Longhorn Engineer site. He also has PCBs (produced by Seeed Studio) available at a very reasonable price.
