Power Supply for NU691
External Power Supply – the board can be powered with a +12V external power supply though a DC connector on the back panel. The rear +12V DC jack accepts plugs with an inner diameter (ID) of 2.5 mm and an outer diameter (OD) of 5.5 mm, where the inner contact is +12V (±5%) and the shell is GND.

Internal Power Supply – the board can be powered via the internal +12V 2-pin power connector, where pin 1 is +12V and pin 2 is GND. The internal 2-pin power connector accepts a JST VHR-2N or TE 1-1123722-2 plug from the power supply. Or use Jetway G01-PWDCJK-2P20-F DC-in cable for alternatively 12V AC adapter.
