An overview of the resulting piece of hardware (there will be a separate video or even two on the software). For me it's been a long and difficult journey within this project and finally I'm happy to present the first revision of the board.
The features turned out to be very impressive:
✔️ All 6 fans controlled by PWM.
✔️ 4 of them with the ability to adjust the supply voltage (3- or 2-wire fans).
✔️ 128 steps of smooth linear voltage adjustment.
✔️ P-channel MOSFETs in DC-DC, wuth ability to work in gate mode (100% fill factor).
✔️ DC-DC output currents up to 4A (15 Watts per channel).
✔️ Continued operation even when the microcontrollers fail.
✔️ DC-DC supply voltage and output voltage sensors.
✔️ 2 digital temperature sensors buses (up to 16 DS18B20 sensors).
✔️ Temperature sensors built into digiPOTs and microcontroller.
✔️ Tracking of the PC temperature sensors (MB, CPU, GPU, HDD) via the control software.
✔️ Power and error indicators + buzzer.
✔️ IPS display 240x240.
✔️ 32.768 kHz crystal for accurate RPM measurement.
✔️ USB connection.
✔️ Different power options: Molex (12V + 5V), Power 12V + USB, Molex + Power 12V, Single PS 5-18V.
✔️ Automatic configuration and connected fans detection.
✔️ Firmware update via USB.
✔️ Mounting holes for the HDD 2.5 holder
Colleagues, ATTENTION!!! I haven't finished the firmware yet, and I've just started coding the management software, so I'm giving a link only to the EasyEDA project. As soon as I finish them, I'll post all the sources and the compiled binaries.
