Fan control: common questions
What microcontroller does the Fan control use?
The Fan control is built around the ESP32-S3-WROOM-1, from the ESP32 family.
How big is the Fan control PCB?
The Fan control measures 50 × 50 mm, has 6 copper layers and is 1.6 mm thick.
How many components are on the Fan control?
56 components, from 23 distinct parts. The full bill of materials is listed on this page.
Where can I download the Fan control design files?
From the MTalon63/PCBs 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 control design in my own project?
It is published under Custom license, which limits how it may be reused; read the license before building on it.
Can I test firmware for the Fan control without the hardware?
Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug ESP32 firmware against it before you order a PCB.
