About the RP-Pico-Fan-Controller PCB

RP-Pico-Fan-Controller is an open source RP2040/RP2350 PCB design by mietzen, published on GitHub under the MIT license. It is a 2-layer board measuring 52 × 80 mm, with 20 components from 6 distinct parts.

Its main chip is the RaspberryPi_Pico, from the RP2040/RP2350 family. By type, the board carries 9 resistors, 1 module and 1 connector.

From the project

Raspberry Pi Pico fan controller

This project aims to create a fan controller based on an RP2040 / RP2350 that can be hand-soldered by anyone and will run on any machine! It uses only the bare minimum of through-hole solder parts to give you:

3 thermal sensors 6 controllable 12V PWM fans

The idea came up when I was building my home server with consumer parts and realized again that most onboard fan controllers don't work properly on Linux.

RP-Pico-Fan-Controller: common questions

What microcontroller does the RP-Pico-Fan-Controller use?

The RP-Pico-Fan-Controller is built around the RaspberryPi_Pico, from the RP2040/RP2350 family.

How big is the RP-Pico-Fan-Controller PCB?

The RP-Pico-Fan-Controller measures 52 × 80 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the RP-Pico-Fan-Controller?

20 components, from 6 distinct parts. The full bill of materials is listed on this page.

Where can I download the RP-Pico-Fan-Controller design files?

From the mietzen/RP-Pico-Fan-Controller repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the RP-Pico-Fan-Controller design in my own project?

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

Can I test firmware for the RP-Pico-Fan-Controller without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug RP2040/RP2350 firmware against it before you order a PCB.
