Prop Clip (#32200)
Prop Plug (#32201)
USB to Serial Adapter for Propeller Circuits
Introduction
The Prop Plug and Prop Clip each provide a USB-to-serial port connection that is convenient for
microcontroller programming and communication. These tiny devices are capable of asynchronous
communication at up to 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 male header, providing in-system programming of
Propeller circuits in bread board, perf board and permanent projects which have the four-pin header. The
Prop Clip is the same product, but designed for attaching to pads on the edge of a PCB. The Prop Clip
could eliminate one part (a 4-pin header) from a PCB design for attaching the Prop Clip to the board.
The electrical schematic for both parts is the same, based on the FTDI232R.
The Propeller Demo Board (#32100) and the Propeller Professional Development Board (#32111) do not
require the Prop Clip or Prop Plug; both of these boards have the USB-to-serial circuit built into the PCB.
The Propeller Proto Board (planned release Q1 2007) accepts the Prop Plug out of the box, and the
layout also supports the USB2SER and the Prop Clip.
Both products include the USB A to Mini B Retractable Cable (#805-00010).
