Arduino Connectors
Five 8-pin, one 10-pin, one 2×3-pin and one 2×18-pin headers footprints (J500 to J507) are implemented
on the board to enable the addition of "Arduino shields" extension cards. These accessory boards are
various and widely available on the market, often custom developed. Due to the PIO multiplexing of the
ATSAME70Q21, various peripheral signals may be connected to each pin. These connectors are
mechanically (location and footprint) compatible with the Arduino R3 shields.
Important:
As the SAM E70 signals have a voltage level of 3.3V, 5V level shields cannot
properly function with SAME70-XPLD.
In addition to its standard IO functionality, the SAM E70 microcontroller can provide alternate functions to
external IO lines available on the J500 to J507 headers.
These alternate functions are:
