Package Contents
The BASIC Stamp HomeWork Board is sold only in quantities of 10. The reason for this is that the board is
intended for the educational market only, to be purchased by educators for use in their classrooms. The kit
includes only the boards – nothing else.
BASIC Stamp HomeWork Board Hardware Design
BASIC Stamp HomeWork Board uses the BASIC Stamp 2 surface-mounted directly to the printed circuit board.
The BASIC Stamp 2 has a wide variety of available support hardware, code examples and applications. Further,
it performs most of the same functions of the newer BASIC Stamps though with less speed and memory. The
BASIC Stamp 2’s technical specifications are shown below (Table 1). Also review the hardware (Figure 1) and
schematic (Figure 2).
