About the Fan control PCB

Fan control is an open source AVR/Arduino PCB design by gajdipajti, published on GitHub under the GPL-3.0 license. It is a board, with 22 components from 14 distinct parts.

Its main chip is the Arduino_Nano, from the AVR/Arduino family. Other key parts include the DS18B20, LM35-LP and AD22100KTZ. By type, the board carries 6 modules, 5 resistors, 3 ICs, 3 transistors, 3 connectors and 1 diode.

It belongs with the displays & leds designs in this gallery.

From the project

A project for controlling 2, 3, and 4 wire DC fans using Arduino or a Raspberry Pi. It also integrates into munin monitoring. Funded by the Free Software Foundation Hungary. The code is under GPLv3. Schematics, drawings, and the documentation is under CC BY-SA-4.0. If you have an idea about how to improve the project, jus file an issue.

Fan control: common questions

What microcontroller does the Fan control use?

The Fan control is built around the Arduino_Nano, from the AVR/Arduino family.

How many components are on the Fan control?

22 components, from 14 distinct parts. The full bill of materials is listed on this page.

Where can I download the Fan control design files?

From the gajdipajti/fan-control repository on GitHub, which has the schematic; the links under Design files point to each one.

Can I use the Fan control design in my own project?

Yes, under the terms of its GPL-3.0 license, which gajdipajti chose for the repository.

Can I test firmware for the Fan control without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug AVR/Arduino firmware against it before you order a PCB.
