Smart fan: common questions
What microcontroller does the Smart fan use?
The Smart fan is built around the ESP-12F, from the ESP8266 family.
How big is the Smart fan PCB?
The Smart fan measures 40 × 32 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the Smart fan?
41 components, from 32 distinct parts. The full bill of materials is listed on this page.
Where can I download the Smart fan design files?
From the VGCH/smart_fan repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.
Can I use the Smart fan design in my own project?
The repository has no license, so all rights stay with VGCH. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the Smart fan without the hardware?
Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug ESP8266 firmware against it before you order a PCB.
