2.2.4.3 Power Supply Connectors
The board has the following power supply connectors:
• 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 +19 (±10%) V DC and the shell is GND. The maximum current
rating is 10 A.

NOTE
External power voltage, 12-19 V DC, is dependent on the type of
power brick used.
• Internal Power Supply – the board can alternatively be powered via the
internal 12-24 V DC 1 x 2 power connector, where pin 1 is GND and pin 2 is
+19 (±10%) V DC.
