Refer to the SAM E70 Series datasheet for further details on the PIO multiplexing and alternate function
selection.
Caution: Like the Arduino Due, SAME70-XPLD runs at 3.3V and the maximum voltage that
the I/O pins can tolerate is 3.3V, connecting higher voltages e.g. 5V to those I/O pin could
damage the board.
Important: not all pins of the shield connectors are necessarily connected to an I/O of the
ATSAME70Q21. Each shield should be checked for compatibility against the SAME70-XPLD
schematics before it is purchased and connected.
4.3.2.1. J500 Header
J500 is a 10-pin header with 2.54mm pitch. It is not populated by default and can be used to connect to
Arduino Shields. It includes PWM, Timer Counter and I
2
C interface signals and analog reference.
