This week, we assembled and tested our prototype PCB. Twain did the initial SMD components, Gary assembled the through-hole components, and Carson modified the software to fit the new layout and did the testing. Fortunately (and maybe surprisingly), we were able to confirm that all of the board functionality that we wanted worked, including:
- The debug/programming interface
- The GPS module
- The display
- The low-power external crystal oscillator
- The energy harvesting (not integrated)
There were a few layout problems that can be fixed in the finalized PCB, but this was still highly successful. Below is an image of us testing the new development board outside, showing both a successful GPS fix and the functioning display.
