Does the BASIC Stamp come in different versions?
Yes. Currently there are four functional versions of the BASIC Stamp and seven physical versions. The BASIC
Stamp line consists of the BASIC Stamp I, the BASIC Stamp II, the BASIC Stamp IIe and the BASIC Stamp IIsx
. The BASIC Stamp I is available in three package types (physical versions) as shown in figures 1a, 1b and 1c
below. The BASIC Stamp 1 Rev. D is a through-hole, socketed package (with prototyping area). The BS1-IC is
a 14-pin SIP with surface-mounted components. The OEMBS1 is a 14-pin SIP in a larger board layout meant for
OEM use (for recreating the entire BASIC Stamp 1 circuitry). It’s important to note the three versions are
functionally equivalent (with the exception of the lack of a Reset pin on the BASIC Stamp 1 Rev. D) but are just in
physically different packages. The BASIC Stamp II , BASIC Stamp IIe and BASIC Stamp IIsx are available in a
24-pin DIP, with surface-mounted components (see Figures 2a, 3 and 4. They are called the BS2-IC, BS2E-IC
and BS2SX-IC, respectively. The BS2-IC is also available in an OEM version (Figure 2b) that is a 20-pin SIP
package.
