The Parallax Propeller Proto USB Board

The Propeller Proto Board USB has all the features of the Propeller Proto Board and includes the USB programming interface on the board for those projects which need the USB interface in the application. For projects which do not need the USB interface after programming, we recommend purchasing the Propeller Proto Board (#32212) and Prop Plug (#32201) since the reusability of the Prop Plug reduces overall cost when programming multiple boards. The Parallax Proto Board Accessory Kit (#130-32212) can be used to provide VGA mouse and keyboard connectors.
