The PropSTICK is USB device which lets you access all the Propeller's pins on a 0.1" format.
The PropSTICK USB is a rapid development tool for the Propeller microcontroller which provides access to all 32 I/O pins on a 0.1" pin spacing format. Intended for use on a solderless breadboard, the PropSTICK USB is also ideally suited for applications where it is socket-mounted on a custom-designed PCB. Great for firmware updates in the field ! The PropSTICK USB is fully assembled.
A 2 foot-long, retractable mini-USB cable is included with each PropSTICK.
IMPORTANT NOTE: The PropSTICK USB is not intended to be plugged into Parallax 40-pin BASIC Stamp board sockets (found on the Professional Development Board, for example). Differences in programming interface, pinouts and operating voltages are the main reason behind this incompatibility.
