All things for the OreSat flatsat
A "flatsat" is a integration and debugging configuration of your satellite that allows you to more easily do system integration, software development, testing, and debugging. It's the "open" satellite that allows you to get at all the signals and ports.
Here's what our OreSat0 flatsat looks like -- note the cards laid out flat on the table, the power supply on the left, the ribbon cable and cards, and the small PC on the upper right (vertical wall) that interfaces everything to the interwebs.
