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.

Getting Started

Note: If you are new to electronics and programming, Pololu recommend starting with the BASIC Stamp Discovery Kit, an excellent introductory kit that comes with everything you need to get started with BASIC Stamp programming and electronics, including a BASIC Stamp 2 module, two printed booklets, and all the basic electronics components necessary to build dozens of fun projects.

To get started with the BASIC stamp you will need the following:

Free programming software that lets you type PBASIC programs in a text editor and compile them for downloading to your BASIC Stamp (the BASIC Stamp editors are available for Windows, Mac, and Linux).
Standard, straight-through serial cable for downloading programs from your computer to the BASIC Stamp. See the BASIC Stamp 2 schematic (143k pdf) for connecting the serial cable to the module.

(Optionally, the Board of Education development board, which is included in the BASIC Stamp Discovery Kit.)
