Signal Tables for Headers and Connectors

This section more clearly defines the pinouts and connector types used in Table 7.

A EPS 8 Pin Power Connector

The EPS 8 Pin Power Connector follows the ATX standard layout and requirements. With one side being Ground and the opposite side with the connector lock being 12V. The NUC 12 Extreme / Pro X Compute element can utilize 12-19V input, while the NUC 12 Extreme / Pro X Kit provides the standard ATX 12V.

D - 20pin Common IO Header

The 20pin Common IO Header utilizes a “Molex Micro-Lock” or equivalent 1.25mm pitch connector which contains signals for the following types of headers.

2x USB 2.0 4 Pin Headers

1x 8pin Internal Dual PWM Fan Header

1x 10pin Front Panel Header (Power LED and Button)

*Note* that a fan-out cable is included that adapts the 20pin Common IO cable assembly into the individual headers listed below. Pin 13 and Pin 20 are powered by the +12V Slot power that is produced by an Element compatible baseboard design. If not connected to a baseboard these two FAN PWM headers capabilities are non-functional. Fan selection should use designs with less than 1A of power required.
