Atmel SAME70-XPLD User Manual

4.3.2.2. J501 Header
J501 is a 8-pin header with 2.54mm pitch. It is not populated by default and can be used to connect to
Arduino Shields. It allows power distribution (3.3V and 5V) to any Arduino Shield connected on the
SAME70-XPLD board.

Pin PCB Marking Function
1 VBAT Not used on SAME70-XPLD board. Connected to testpoint TP910
2 IOREF ADVREF. Reference voltage for the analog inputs of the SAM E70
microcontroller. Actually connected to 3.3V.
3 RESET System reset
4 3V3 Main 3.3V supply - generated by the on-board regulator.
5 5V0 Main 5.0V supply (ouput or input). In case that pin is used as power supply
source, do check the recommendations given in Power Sources on page 8
section.
6 GND System ground
7 GND System ground
8 VIN Not connected by default. Optional 5Vcc supply for any Arduino Shield.
Info: Pin 8 is connected to the SAME70-XPLD board through an 0R serial resistor. It is
necessary to mount 0R resistor R623 to enable the functionality.
