Electronics-Salon 4X Prototype Breakout PCB Shield Board Kit for Raspberry Pi 3 2 B A , Breadboard DIY.

The boards themselves are made from a nice, thick FRN and the headers, screws and standoffs are of good quality. I wish the screws were maybe 2-3mm longer but they fasten just fine. I also like the layout of the board, with rails for both 3.3 and 5v and the ground rail on the other side of the board to avoid possible shorts.My only real complaint is that the pads aren’t particularly durable if you need to remove components or wires once they’ve been soldered. With my iron set at 400C I tried moving a piece of header I had put in the wrong place and I managed to pull up two of the four pads it was soldered to. I’m not new to soldering so I have a reasonable expectation about how much heat and force I can use before pads pull up, and these came up easier than I would have expected.Overall though, as long as you get your component placement right the first time, you should be happy with these boards. I can also confirm they work perfectly with the Pi Zero and Zero W, and that the standoffs closest to the GPIO header line up with the Zero’s screw holes for mounting.
