Great quality and attention to detail.

Arrived on time and even had Thank you post-it handwritten message form the seller inside! The board is very good start for building your own DIY eurorack synth. Recommended!

Great power bus for a smaller system, quick to build.

I'm a new Eurorackist and am using this in a home-built 84HP Eurorack skiff. Fourteen Doepfer connections is probably overkill (edit in September: No, I've filled them all!), but I wanted the additional 1U-type connectors. I've not populated the Analogue Systems connections, as I don't have any modules requiring them. Only thing that would make this better is resettable fuses in the bus somewhere - there's no help if you start drawing more power than the board can handle. I'm doing both modules and cables DIY, so it _should't_ happen, but I'm still concerned.

Hi Alyn!
Yes, the power connectors are filled pretty quickly in a modular system! There's never enough modules and never enough power connectors!

On the lack of resettable fuses, I totally understand your concerns.
The power bus board itself doesn't require a fuse. It can handle a lot of current and your PSU must have a fuse anyway. In case of a short circuit (several amps), it's the PSU fuse who blows.

A faulty module shouldn't damage the orther modules.
The only advantage of having fuses on the bus board is to separate the faulty circuit and to prevent the whole system to stop functionning.
However, it's complicated to design such protection: What's a faulty module? How much current a module is reasonably supposed to draw to stay safe?
For example, a VCO draws around a couple tens of miliamps while some big multifunction modules with LEDs and µC or a tube VCA draw hundreds of mA. Maybe more.
So, placing, say, a 200mA fuse on each connector would prevent some modules to function properly and maybe wouldn't be enough to prevent damaging a faulty module.

Besides, the worst thing a module can experience is having a reversed power input. (Wrong cable, misconntected connector, badly powered bus...)
The best way to keep everything safe is having some protection diodes or Mosfets on each module power input.
