BASIC Stamp 2
The BASIC Stamp 2 is available in the above two physical packages. The
BS2-IC (Figure 1.4) uses surface mount components to fit in a small 24-pin
DIP package. The OEMBS2 (Figure 1.5) features an easier-to-trace layout
meant to aid customers who wish to integrate the BASIC Stamp 2 circuit
directly into their design (as a lower-cost solution). The OEMBS2 is
available in either an assembled form or a kit form. Both packages are
functionally equivalent.
