I designed the first revisions of the standalone and Arduino compatible PCBs for the Trackuino project.
I was instrumental in the development of the platform and am proud of the fact that the first launches of the Trackuino were successfully tracked and recovered.
The project was started in Spain by Javier Martin and I became involved after reading a blog post were he was looking for assistance in laying out a circuit board.
Trackuino board design and low-volume production
During the course of creating my own boards I started selling small quantities of extra PCBs and modules to other members of the ballooning community.
