• External Power Supply – the board can be powered through a 12 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 through +19 (±10%)

V DC and the shell is GND. The maximum current rating is 3 A.

• Internal Power Supply – the board can alternatively be powered via the internal Molex Micro-

Fit 3.0 2 x 2 power connector, where pins 1 and 2 are +12 (±10%) through +24 (±10%) V DC

and pins 3 and 4 are GND. The maximum current rating for this connector is 10 A.
