Desktop boards with a 19 VDC power connector

These boards can use the following power supplies:

  • External Power Supply – the board can be powered with a 19 VDC external power supply through the 19 VDC connector (A in the image below) on the back panel. The back panel connector accepts plugs with an inner diameter (ID) of 5.1 mm and an outer diameter (OD) of 7.4 mm, where the inner contact is 19 (±5%) VDC and the shell is GND.
  • Internal Power Supply – the board can alternatively be powered via the onboard 19 VDC 1 x 2 power connector (B in the image below). The internal 1 x 2 power is a Molex 5566-2 header which accepts a Molex 5557-02R connector from the power supply.

Use of an external 19 VDC power supply is preferred.
