Didn't see this until today, but am happy I wasn't imagining things about the lead-time being broken when I tried it (about 18 months ago I think?)

Will report back results when I get a chance to try the latest version. Thanks for the efforts keeping this updated.

After continuously having issues with my own controller design for a while I decided to join the family and implemented the design into my controller:


It is 100% compatible with the existing version, but has the power supplies (24V,+-12V and 5V), fiber TX&RX and the LEDs on board, and because of this I gave it the c suffix (for compact). (even if it is 10cm larger in width and height :P)
The PCB ist sized to slide into a cheap extruded aluminium box like this one (the 110mm version):

I also moved the GDT driver to a daughter board, so it can be replaced with a digital isolator board for use with gate driver ICs.
Because of this the FAN power is now only 12V though, to keep the 24V (and when using gate drive ICs also mains) completely isolated from the control logic.

The design files (for altium) are here: https://github.com/TMaxElectronics/UD3c (un-tested at the moment)
If you have the time I'd appreciate any suggestions for improvements. The repo also has a PDF version of the schematic ;)
