USB Input / Output Board is a spectacular little development board / parallel port replacement featuring PIC18F2455 / PIC18F2550 microcontroller. USB IO Board is compatibile with Windows / Mac OSX / Linux computers. When attached to Windows IO board will show up as RS232 COM port. You can control 16 individual microcontroller I/O pins by sending simple serial commands. USB Input / Output Board is self-powered by USB port and can provide up to 500mA for electronic projects. USB IO Board is breadboard compatible. Simply solder included 12-PIN & 8-PIN headers on the bottom side of the PCB and the board can be plugged into a breadboard for quick prototyping.
