The KiCad project lives in the ferrybig/70w-fan-controller repository on GitHub; these links point at the commit this page was built from.

Fan controller old: common questions

What microcontroller does the Fan controller old use?

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

How big is the Fan controller old PCB?

The Fan controller old measures 60 × 60 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Fan controller old?

35 components, from 23 distinct parts. The full bill of materials is listed on this page.

Where can I download the Fan controller old design files?

From the ferrybig/70w-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 old design in my own project?

The repository has no license, so all rights stay with ferrybig. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the Fan controller old 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.
