Fan controller with ch: common questions

What microcontroller does the Fan controller with ch use?

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

How big is the Fan controller with ch PCB?

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

How many components are on the Fan controller with ch?

46 components, from 27 distinct parts. The full bill of materials is listed on this page.

Where can I download the Fan controller with ch design files?

From the ferrybig/70w-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 Fan controller with ch 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 with ch 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.
