Fan
===

The phyCORE-AM65x Carrier Board provides fan connectivity via a 2-pin Hirose connector at X28. The fan is intended to be mounted directly to the processor heat sink for thermal management, both of which are included in the phyCORE-AM65x development kit. The 5V power supplied to the X28 connector is regulated from the VDD_12V0 power rail through an LP3878-ADJ regulator at U40. The regulated 5V output is enabled by driving X_GPIO1_49 high. When X_GPIO1_49 is pulled low, the 5V supplied to the fan connector will be turned off. The default behavior of the phyCORE-AM65x is to keep the fan running at all times.
