FanControl: common questions
What microcontroller does the FanControl use?
The FanControl is built around the ESP-12E, from the ESP8266 family.
How big is the FanControl PCB?
The FanControl measures 72.8 × 38 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the FanControl?
81 components, from 39 distinct parts, with part numbers taken from the project's own BOM. The full bill of materials is listed on this page.
Where can I download the FanControl design files?
From the bakadave/fanControl repository on GitHub, which has the KiCad layout, the schematic and the BOM; the links under Design files point to each one.
Can I use the FanControl design in my own project?
The repository has no license, so all rights stay with bakadave. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the FanControl 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.
