BASIC Stamp 2p
The BASIC Stamp 2p is available in the above two physical packages.
Both packages use surface mount components to fit in a small package.
The BS2p24-IC (Figure 1.10) is a 24-pin DIP package. The BS2p40-IC
(Figure 1.11) is a 40-pin DIP package. Both packages are functionally
equivalent accept that the BS2p40 has 32 I/O pins instead of 16.
