2.4 Power Sources
Two options are available to power up the SAMA7G54-EK board:
- Through an external AC to DC +5V wall adapter connector (J1)
- Through the USB Micro-AB connector on the USBA port (J7)
| Electrical Parameter | Value |
|---|---|
| Input voltage | 5 VDC |
| Maximum input voltage | 6 VDC |
| Maximum 3.3 VDC current | 300 mA |
CAUTION: The SAMA7G54-EK board
runs at a 3.3V voltage level logic. 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.
