Fan Connector and Power Configuration
Jumper X63
Configuration

12 Volt fan (default)

5 Volt fan
Connector Type
X14: 3 pin 2.54mm grid fan connector,
X63: 3 pin 2.54mm grid jumper.
Note
congatec COM Express™ modules provide signals for fan control. This has been implemented through the use of some reserved pins.
COM Express™ module pin C77 provides the FAN_TACHOIN signal that is attached to pin 3 of the fan connector X14 found on the conga-CEVAL.
This signal must receive two pulses per revolution in order to produce an accurate reading and therefore a two pulse per revolution fan is
recommended.
