Custom PC fan controller for Athena Power rackmount computer cases

This repository contains the circuit board and firmware for a fan controller which I designed to replace the splitter which ships with the Athena Power RM-1UC138 rackmount computer case.

Instead of running the bundled 12 V fans at full speed, this controller allows you to install your own PWM fans, and set a fixed speed via a potentiometer, with no involvement from the motherboard.

Fan controller athena power: common questions

What microcontroller does the Fan controller athena power use?

The Fan controller athena power is built around the ATtiny85-20P, from the AVR/Arduino family.

How big is the Fan controller athena power PCB?

The Fan controller athena power measures 70 × 26.8 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Fan controller athena power?

8 components, from 5 distinct parts. The full bill of materials is listed on this page.

Where can I download the Fan controller athena power design files?

From the mike42/fan-controller-athena-power repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

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

Yes, under the terms of its GPL-2.0 license, which mike42 chose for the repository.

Can I test firmware for the Fan controller athena power 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.
