The BASIC Stamp 2p40 serves as the brains inside of electronics projects and applications that require a programmable microcontroller. It is able to control and monitor timers, keypads, motors, sensors, switches, relays, lights, and more. Programming is performed in an easy-to-learn language called PBASIC. All vital components (processor, clock source, memory, power regulator) are provided on the BS2p40's tiny PCB; just connect power and go! For lower-cost OEM solutions, the processor (PBASIC2p40 interpreter) and other components are available for integration into your PCB. The BS2p40-IC is useful for those that have previous experience with the BS2 and would like more speed, variable space, program space, I/O pins, or built-in support for character LCDs and the I2C and 1-Wire protocols; for example, LCDIN / LCDOUT, I2CIN / I2COUT, OWIN / OWOUT and POLLIN / POLLOUT / POLLMODE / POLLRUN / POLLWAIT (see BASIC Stamp Syntax & Reference Manual for more details) For customers that require true multi-processing or video generation, we highly recommend the Propeller microcontroller.
