It's astonishing 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 BS1's tiny PCB; just connect power and go! The BASIC Stamp 1 (BS1-IC) is an ideal fit for applications that don't require the speed, I/O, and memory of the BASIC Stamp 2 series of microcontrollers. Projects needing small, permanent soldering area for circuitry may benefit from combining the BS1-IC with the BASIC Stamp 1 Carrier Board (#27110) or simply using the BASIC Stamp 1 Project Board (#27112). For lower-cost OEM solutions, the processor (PBASIC1 interpreter) and other components are available for integration into your PCB. However, due to the fact that modules cost less than $20 in large quantities, it's a strong candidate for high volume applications.
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, then the Propeller microcontroller is going to be the best option.
