BASIC STAMP 2 MODULE

The BASIC Stamp is a classic! Originally introduced in 1995, this juggernaut has seen quite a long run. The BASIC Stamp BS2 is a microcontroller developed by Parallax, Inc. which is easily programmed using an easy-to-learn language called PBASIC.  It is called a “Stamp” simply because it is close to the size of an average postage stamp. You can use the BASIC Stamp 2 to control and monitor timers, keypads, motors, sensors, switches, relays, lights, and more.

All vital components (processor, clock source, memory, power regulator) are provided on the BS2's tiny PCB; just connect power and go! The BS2 uses a PIC16F57 as the main processing unit and all other vital components (oscillator, memory, voltage regulator) are included; the board even has an RS-232 to TTL converter, so you can connect it directly to your PC. See related items below for serial cable and breakout board.

The BS2-IC is widely used in educational, hobby, and industrial applications and is recommended for first-time BASIC Stamp users because of plentiful resources (documentation, source code, and customer projects) that are available online and in print. We also carry a number of other educational kits based around the BS2, check them out in the related products below.
