The BS1USB is a handy little device is perfect for adding a user-definable function to your PC.

It's amazing what you can accomplish with this well-proven microcontroller and its simple PBASIC 1 language.

All vital components (processor, clock source, memory, power regulator) are provided on the tiny PCB; just connect power and go!

For customers that require a more powerful microcontroller, we highly recommend the BASIC Stamp 2 series controllers; if true multi-processing is what is needed for your project or applications, than the Propeller microcontroller is going to be the best option.
