I have some PIC18F4550s lying around, and I want to play with the USB features of this chip, therefore I made this breakout board. It contains enough components to get the PICMicro running, and nothing more, all the pins are routed to pin-headers to use with an experimenter board.

Features:

  • ICSP connector (In-Circuit Serial Programming, AKA PicKit 2 & 3)
  • USB-B Connector
  • 20Mhz clock crystal
