This is simple prototype board for development of USB application with PIC18F4550 microcontroller. The power of the 18F4550 is that it has USB hardware built into it so that you can program different USB stacks directly onto the IC. Microchip provides these free USB solutions for their microcontrollers which are openly available. USB HID Class firmware you can build mouse or other Himan Interface Device for Windows, USB CDC Communication class device, USB Mass Storage firmware - add your own USB disk drives to your computer, USB-to-RS232 driver. The prototype space allow you easy to add on sensors, relays and other peripherial devices to interface to USB. The board can take power from USB or from external supply with small jumper selection.

ICSP/ICD connector for programming with PIC-MCP, PIC-MCP-USB, PIC-PG1,PIC-PG2, PIC-PG3 or PIC-PG4 and programming and debugging with PIC-ICD2, PIC-ICD2-POCKET, PIC-ICD2-TINY
