8 Relays Card V2 for Raspberry Pi
I built a DIY PiKVM connected to an 8-port switch to reduce trips to the computers in the loft. This left out the ATX power control for which I needed eight switches. Closing the motherboard power switch pins for half a second to power up and for four seconds to power down works a charm and this uses voltages low enough to warrant shielded signal cables. My first attempt was a Modbus PoE relay which was plagued by bad software and ended up back to the vendor.
This board is a breath of fresh air. Git clone, build install on clean (plus git) RPi OS 64 lite had the relays clicking within minutes of assembly. There are Node Red and Python modules as well for those with different use cases. I was happy not to make it too easy to power down a target computer. The connectors may look a bit puzzling but they are actually sockets for small three-prong plugs that house the screw terminals. This makes it easier to build a cable assembly and just plug the machines in on site without a screwdriver.
There is ample room for expansion by stacking additional hats to the same Pi and everything runs off the single power supply. All-in-all a properly engineered product with good open-source software in tune with the Pi ecosystem.

Everything is fine with the product, the delivery was not fast but the cause is the hungarian government not the PiHut
