Automation, sensing and robotics • Fan Control System

Hi there,

I apologize if a similar topic already exists. I just started my project and would like to ensure that I have a good design and have chosen the right components.

Project Description:
The goal is to control fans via PWM and monitor their RPM.
Communication will be handled through USB Serial Input/Output with simple commands such as:

• TURN ON/OFF – Turns all connected fans on or off
• FAN1 50 – Sets FAN1 speed to 50%

For now, I plan to control two identical fans. Below is a list of components I have decided to purchase and those I currently own:

Components:

• 1x Raspberry Pi Pico 2
• 2x 12V PWM Fan (ARCTIC S8038-10K)
• 1x 12V Power Supply (Avacom 12V 5A 60W)
• 1x MOSFET (IRL3803PbF)
• 1x Schottky Diode (flyback protection, SEMTECH SR860)
• 1x 10kΩ Resistor

Wiring:

I already have a working code, and it seems to function well. However, I want to confirm that my component choices and wiring are correct. Once I receive confirmation, I plan to open-source the project, and any feedback on the code will be also greatly appreciated

Thank you very much!
LT
