2.2.4.4 Power Supply Connector
The board has the following power supply connector:
• External Power Supply – the board can be powered through a 12-19 V DC connector on the
back panel. The back panel DC connector is compatible with a 5.5 mm/OD (outer diameter)
and 2.5 mm/ID (inner diameter) plug, where the inner contact is +12 (±10%) V DC and the
shell is GND. The maximum current rating is 3 A.
NOTE
External power voltage, 12-19 V DC, is dependent on the type of power brick used.

NOTE
The Auxiliary Power Connector is a limited voltage source (output) for 5V Standby and the voltage
supplied to the board (typically 19V DC) for use by expansion peripherals. The Auxiliary Power
Connector is limited to 1.5A max (fused).
