For example, consider the open-source GPS shield developed by Adafruit Industries shown
in
Figure 4.2
.
This shield supports any of the four most popular GPS modules and stores
data on a standard DOS-formated SD lash memory card. For scientists doing ield work (e.g.
environmental scientists tracking water quality in the Great Lakes) after collecting the data,
software or a spreadsheet. The pins indicated in
Figure 4.2(b)
are required for the SD card. The
GPS module also requires pins connected, but they can be jumpered to any of the spare Ar-
duino pins. Up to eight other pins may be required depending on whether you implement SD
card detection, status indication, and other features.
