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



Eagle files:  PIC18F4550 USB ICSP breakout board

I have just finished mounting the µC board, to test the firmware and, after a little trimming, everything worked. The fact that the board connects directly to the PICkit2 programmer, means that I can program it , and test it while the thing is on. I have updated the code in the SVN, to reflect the changes. All there is left, are three holes in the front and oh I gotta put a lid on it.

I have just finished testing a prototyping board I have designed for the PIC18F2550, that I will be using in a project I am doing for a friend. The board is designed to interface with the PICKit 2, programmer/debugger, has an on board 5 Volt regulator, and pads for a serial port through the MAX232 line driver/receiver. This is not rocket science, just a nice PIC18F2550 to breadboard converter.
