Based on the work of Brian Schmalz, the USB Bit Whacker (UBW) is a small PIC18F2553 board with a pre-programmed command interpreter for basic input and output control. When attached to a Windows/Max OS X/Linux computer, the UBW will show up as an RS232 Com port. You control the individual I/O pins on the PIC through simple serial commands. Board comes fully tested, preprogrammed, and assembled as shown.

The 18F2553 comes pre-programmed with a USB bootloader. This means you can create HEX files using any PIC compiler or assembler and then load that HEX file onto the PIC without an external programmer - directly over USB. Board power is also obtained over USB.

Please see the UBW home page for more information.
