Resources and Downloads
You may download the schematic for the PDB free from our website by typing in the product number
(28138) into our search box. Please refer to the PDB schematic for detailed information about each
circuit on the board. For additional information on some of the integrated circuits included on the PDB,
such as the L293D, DS1307, LM386 or MAX232E, please download the manufacturer’s datasheet from
their respective websites. You can also search Google for this information as well as additional
application notes.
Solderless Breadboard
Most experiments will involve components placed in the solderless breadboard. Before the breadboard is
used, power busses should be installed.
connections), connect the buss rails as suggested below. By using looped wires to connect the power
busses to Vdd and Vss, one or both can be used as an “emergency switch” to remove power from the
breadboard if required.
Installing Microcontroller Modules
Three sets of sockets are provided that allow the PDB to accommodate the BS1-IC module, the 24 or 40-
pin BASIC Stamp modules, the 24-pin Javelin Stamp module, as well as the SX28AC/DP microcontroller.
The SX28 socket is mechanically separated from the other modules and allows the SX28AC/DP to run
with all BASIC Stamp and Javelin Stamp modules except the BS2p40. The table below lists socket and
electrical compatibility, and which modules can be connected and used at the same time.
