BASIC Stamp 2sx Module - Supports the BS2 command set with more data and program space at more than twice the execution speed. BASIC Stamp 2 Module – Ideal for beginners yet quite powerful, with a vast resource base and sample code. The BS2 is the core of our Stamps in Class program. BASIC Stamp 2p24/40 Modules - In addition to more speed and data space, special commands support I/O polling, character LCDs, and I2C and 1-Wire protocols. The BS2P40 has these features plus 16 additional I/O pins. BASIC Stamp 2e Module - Perfect for those who have experience with the BASIC Stamp 2 and would like more data and program space. BASIC Stamp 2pe Module - BS2p command set paired with lower power consumption and more memory for battery-powered data logging applications. BASIC Stamp 2px Module - Our fastest BASIC Stamp microcontroller supports the BS2p command set as well as special I/O configuration features.
