Basic Stamp Modules ( BS2 , BS2SX, BS2P24, BS2P40, BS2PE )

As a rapid prototyping tool for engineers, an affordable controller for hobbyists, and an easy-to-learn platform for technology students, the BASIC Stamp microcontroller prospers in many fields. Common uses include classroom robotics and lab projects from middle schools to universities, scientific field research tools, process control systems, and custom or lower-volume engineering projects. A wide base of sample applications and source code is available free online.

A BASIC Stamp module is a single-board computer that runs the Parallax PBASIC language interpreter in its microcontroller. The developer’s code is stored in an EEPROM,which can also be used for data storage. The PBASIC language has easy-to-use commands for basic I/O, like turning devices on or off, interfacing with sensors, etc. More advanced commands let the BASIC Stamp module interface with other integrated circuits,communicate with each other, and operate in networks.

The free BASIC Stamp Editor Software is the programming environment for all BASIC Stamp modules, and custom devices built with Parallax PBASIC Interpreter chips. A built-in Debug Terminal supports bidirectional communication between the BASIC Stamp and the PC during run-time.
