SAMA5D2 Xplained Ultra [USER GUIDE]

Atmel-44028C-ATARM-SAMA5D2-Xplained-Ultra-User Guide_13-Oct-16

Power Source

Several options are available to power up the SAMA5D2-XULT board:



USB-powered through the USB Micro-AB connector (J23 - default configuration)



Powered through a rechargeable battery Li-polymer 3.7V connected to J3 or J4



Powered through the USB Micro-AB connector on the Atmel Embedded Debugger (EDBG) interface (J14)

2.1

Power up the Board

Unpack the board, taking care to avoid electrostatic discharge. Connect the USB Micro-AB cable to the connector

(J23). Then connect the other end of the cable to a free USB port of your PC.

WARNING

Unlike Arduino Uno boards, the SAMA5D2-XULT board runs at 3.3V. The maximum

voltage that the I/O pins can tolerate is 3.3V. Providing higher voltages (e.g., 5V) to

an I/O pin could damage the board.
