strange, non-deterministic behavior. ex: running the same code that repeatedly prints over uart, the output would appear in the terminal apparently at random intervals, which varied over time and across programming iterations

12

not epoxied. was bonded to attempt to see difference in lighthouse performance without epoxy. never got it to successfully program
