Nvidia Jetson Fan Control

The tachometer signal tells the jetson what the speed of the fan currently is and the pwm signal allows the jetson to control the fan speed.

Nvidia jetson fan control. The silkscreen has been fixed in later versions. This article explains how to use the gpio pins and interface them to control motors leds and other electronic components. 5 22 19 add rpi spreadsheet helper thanks stephen warren from nvidia 5 12 19 add formal signal names. The mounting holes of the nf a4x20 5v pwm and nf a4x10 5v pwm align with the holes in the heatsink of the nvidia jetson nano developer kit.

Bsp provides active cooling by fan management through the cooling device pwm fan which provides. Bsp provides thermal management using fan control and throttling of various clocks in the system. Jetson nano j41 gpio pins on this early board note that pins labeled 6 8 should be 8 and 10. Tested on a jetson nano but should work on other boards as well.

The fan gets power from the jetson from the gnd and 5v pins. Fan speed control by programming the pwm controller. The pinout diagram below shows the different uses of the pins. The regular 12v pwm versions will not work.

You will need a 5v pwm fan for this to make any sense. Pin 1 is marked 1.
