Additional Device Compatibility
While the board initially comes populated with a ULN2003A device, this board is compatible with many
other pin-to-pin devices that perform a similar function. As shown in
Figure 14
, the Boosterpack has the
landing pattern for both the 16-pin D (SOIC) as well as the 18-pin DW (WIDE SOIC) package.
Figure 15
shows the Boosterpack populated with the ULN2803A device.
If the ULN2003A device is depopulated, the following list of devices can be populated in order to be
evaluated.
