Description
This project is still in development so lot of things can be untested or not working at all!
ESP32 10 channel pwm fan controller with control over tcp sockets and serial,
temperature readout from onewire temperature probes (unlimited count, board have 2 ports),
fan control routine (automatic - 20 points temperature curves with option of multiple
temperature inputs and one external temperature value set by control interfaces, manual)
for 10 separated channels with rpm readout from tacho sensor and led strip control routine with
predefined effects (some of them use the temperature probes to be able to display temperature).Features
- 10 Channels for PWM fans
- Automatic or manual fan speed control
- Automatic control with 20 point curves with option for multi source temperature input for each fan
- 2 Channels for one wire temperature probes
- 2 Channels for RGB adressable led strips
- Predefined effects and some even reacts to temperature
- Support for both 5V and 12V warriants
- Integration for Argus Monitor
- Power by molex or barrel jack (selectable by jumper when stepdown is present)
Todo
- Publish Schematics for board

Questions
How big is the FanController PCB?
It measures 100 × 79.7 mm and has 2 copper layers, 1.6 mm thick.
What parts does the FanController use?
164 parts, built around the BC847B,215-JSM, BSS138, S3P-VH(LF)(SN) and M5082RK-04P. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the FanController KiCad files?
From the Matesxs/ESP32FanController repository on GitHub, at the commit this page was made from: the board is Schematics/FanController.kicad_pcb and its schematic Schematics/DI_Tach.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the FanController design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
