STAMP 2: STAMP 2P, 2E, 2I, 2SX, and a STAMP 2 original equipment manufacturer
(OEM) version, shown in Fig. 1-4—a true testament to a truly successful product.
The BASIC STAMP 2 (BS2-IC) is the single most popular BASIC STAMP module and
is widely used in educational, hobby, and industrial applications. This module normally has
2 kbytes of program space and 16 I/O pins. A serial PC interface provides enhanced debugging
features.
Advantages of STAMP 2
The BASIC STAMP 2P (BS2P24, BS2P40) has several advantages over all previous
BASIC STAMPs, including commands for interfacing with parallel LCDs, I2C devices,
Dallas Semiconductor 1-Wire parts, and a polled interrupt capability. The BS2P is 3 times
faster than the BS2-IC and 20 percent faster than the BS2SX-IC and is available in a pincompatible
format to other BS2 variants, or as a 40-pin module (with 16 extra I/O pins!).
The BASIC STAMP 2SX (BS2SX-IC), using the Ubicom SX microcontroller, is 2.5
times faster than the BS2-IC. It has the same program memory as a BS2P but does not have
