Ok, I got the boards from Seeed today so I took one pcb, cut it up into 24 individual pieces and soldered up one of them. It works just fine with a atmega328... But damn, the individual boards sure are small, but not completely unlike the rendering.
These are great for bread boarding, you can have a bunch of different values on hand and just pop one in and try it. Specially when your to lazy to check the data sheet or someone left the value off on the schematic, Bom. Cool.
