Fanctrl: common questions
What microcontroller does the Fanctrl use?
The Fanctrl is built around the ESP32-C3-WROOM-02, from the ESP32 family.
How big is the Fanctrl PCB?
The Fanctrl measures 40 × 86 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the Fanctrl?
33 components, from 23 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 Fanctrl design files?
From the burgrp/accuwatt 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 Fanctrl design in my own project?
The repository has no license, so all rights stay with burgrp. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the Fanctrl 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.
