Microchip PIC18F4XJ5X USB Demonstration Board

The Microchip Technology PIC18F4XJ5X Full-Speed USB Demonstration Board is designed as an easy-to-use evaluation platform for Microchip's full-speed, USB PIC18F4XJ5X families of microcontrollers. The board can be operated as a stand-alone device. Alternately, for additional demonstration functionality, the board can be used in conjunction with the PIC18 Explorer Board or PICDEM™ HPC Explorer Board. All members of the PIC18F4XJ5X families of microcontrollers fully support USB 2.0 full-speed and low-speed serial communications at signaling speeds of 12 Mbps or 1.5 Mbps. The demonstration board package provides all of the hardware and software needed to develop USB compliant communication solutions.
