The BASIC Stamp 2 module 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, which is detailed in the starter kit that includes the BASIC Stamp 2, the BASIC Stamp Discovery Kit.

The BS2-IC is widely used in educational, hobby, and industrial applications. Plentiful resources including documentation, source code, and customer projects are available online and in print.
