One of the leading suppliers of programmable microcontrollers is Parallax, Inc. The company is located in Rocklin, CA — a short commute from Sacramento. They offer a complete line of BASIC Stamp modules, SX chips, and an innovative assortment of robotics. Parallax has historically been close to the microcontroller architectures, which they support. Most recently, they have put this skill to use by designing the Propeller processor entirely on their own, transistor by transistor. The company remains privately owned and is doing gross yearly sales of approximately eight and a half million dollars.
