SiLabs C8051F410 micro controller

Silicon Labs C8051F410 microcontroller soldered to a Proto-Advantage PA-0091 header. Proto-advantage will acquire the uController and solder it to their header for you! Great for prototyping.
This was wired up for ENSC E-123 course at Harvard Extension (following Learning the Art of Electronics, by Tom Hayes).
