About the Fan controller PCB

Fan controller is an open source AVR/Arduino PCB design by GewoonMaarten, published on GitHub under the MIT license. It is a 2-layer board measuring 50 × 40 mm, with 10 components from 9 distinct parts.

Its main chip is the ATmega328P-PU, from the AVR/Arduino family. By type, the board carries 3 connectors, 2 capacitors, 1 IC, 1 crystal, 1 switch and 1 resistor.

Fan controller: common questions

What microcontroller does the Fan controller use?

The Fan controller is built around the ATmega328P-PU, from the AVR/Arduino family.

How big is the Fan controller PCB?

The Fan controller measures 50 × 40 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Fan controller?

10 components, from 9 distinct parts. The full bill of materials is listed on this page.

Where can I download the Fan controller design files?

From the GewoonMaarten/fan-controller repository on GitHub, which has the KiCad layout; the links under Design files point to each one.

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

Yes, under the terms of its MIT license, which GewoonMaarten chose for the repository.

Can I test firmware for the Fan controller 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.
