Microcontroller Module Compatibility
The sections that follow give details on installing the various microcontroller modules compatible with the
PDB.
connection.
Using the BS1-IC Module
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 at
right. The BS1-IC can be programmed through a
standard serial port when using the BS1 Serial Adapter
(#27111, available separately).
Note: The BS1-IC module may be used in conjunction
with an installed SX28AC/DP micro.
Using a 24-pin BASIC Stamp or Javelin
Stamp Module
To install a 24-pin BASIC Stamp or Javelin Stamp module,
an installed BS1-IC module must be removed. Carefully
align the pins of the 24-pin module noting the Pin 1 dot on
the PDB as shown in the illustration at right.
The 24-pin BASIC Stamp or Javelin Stamp module can be
programmed through a standard serial port.
BASIC Stamp and Javelin Stamp modules may be used in
conjunction with an installed SX28AC/DP micro.
Using the BS2p40 Module
To install a BS2p40 module, an installed BS1-IC module
and the SX28AC/DP must be removed. Carefully align the
pins of the 40-pin module noting the Pin 1 dot on the PDB
as shown in the illustration at right.
The BS2p40 module can be programmed through a
standard serial port.

Before proceeding, move the power switch to the OFF position and remove the input power
CAUTION: The SX28AC/DP micro must be removed before installing and using the BS2p40.
Having both modules installed at the same time could cause an I/O pin conflict that could
lead to damage to one or both of the modules.
