This is a small board with a load switch to allow a Raspberry Pi to temperature control a fan via GPIO3. It can be used to toggle power for other devices using up to 1A.

There are multiple variants of the board depending on orientation and fan connector pin pitch.

• Vertical 2.54mm (0.1")
• Vertical 2mm
• Horizontal 2.54mm (0.1")
• Horizontal 2mm

Please ensure you select the correct option for your usage, if unsure please contact us first.

The Fan controller should be connected to the first 6 pins on the header where it uses 5V, GND and GPIO 3 (check the photos for the correct orientation).

To automatically cool your Raspberry Pi when it starts to warm up add the following to your /boot/firmware/config.txt and restart the Pi.

dtoverlay=gpio-fan,gpiopin=3,temp=80000

Most PCB have FAN +/- pin markings, older PCB just have a BLACK marking on the negative pin (on all models the negative fan pin is the pin closest to the IC).
