Preparing the Solderless Breadboard
Most experiments will involve components placed in the solderless breadboard. Before the breadboard is
used, power busses should be installed.
Using 24-guage solid wire (also suggested for circuit
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
The sections that follow give details on installing the various microcontroller modules compatible with the
PDB. Before proceeding, move the power switch to the OFF position and remove the input power
connection.
Using the BS1-IC Module
Programming Connection
USB
DB-9
BS1-SA
SX-Key
To install the BS1-IC, an installed BASIC Stamp or Javelin Stamp module must be removed. Carefully
align the pins of the BS1-IC module with the SIP socket such that the BS1-IC components are oriented
toward the solderless breadboard, as shown in the illustration below.
The BS1-IC can be programmed via the USB port or through a standard serial port when using the BS1
Serial Adapter (#27111, available separately) or the original parallel port programming cable (requires
DOS editor that is no longer supported).
Note: The BS1-IC module may be used in conjunction with an installed SX28AC/DP micro.
