:: Shield Pin Usage ::
With the growing number of shields available for the Arduino, it would be nice to know which Arduino pins are utilized by each shield. This page is intended to provide that information and make it readily available.
Note that the information on this chart for most shields that use the SPI bus applies only to Uno and other ATmega328P/ATmega168 based boards. Any correctly designed shield will connect the SPI lines(MISO, MOSI, SCK) via the ICSP header instead of the standard Arduino I/O pin headers because the SPI is found on different pins depending on the board(see the "Connections" chart at https://www.arduino.cc/en/Reference/SPI). Any such shield that is advertised as "Mega Compatible" will be connected this way. This page should be changed to indicate ICSP header pin usage.
When you add a board, please add it alphabetically.
