 ****************
 
 GPIOs accessed by the shield peripherals must be identified using the
-shield GPIO abstraction, for example from the ``arduino-r3-header``
+shield GPIO abstraction, for example from the ``arduino-header-r3``
 compatible.  Boards that provide the header must map the header pins
 to SOC-specific pins.  This is accomplished by including a `nexus
 node`_ that looks like the following into the board devicetree file:
