Prop Plug Serial Programing Tool
By Parallax (32201)
The Prop Plug provides a USB-to-serial port connection that is convenient for micro-controller programming and communication. This tiny device is capable of asynchronous communication at up to a 3 M baud with both 3.3-volt and 5.0-volt devices such as the Propeller and BASIC Stamp. The Prop Plug slips onto a 4-pin, 0.1" spaced header, allowing both printed circuit boards and breadboards to provide in-circuit programming capability.
