Putting together a couple Quarks, and the instructions say that all through-hole components need to be installed on the same side of the board, and that if you choose top-side installation, you can't use a screw terminal block, therefore need to solder deployment wires right to the board. If you choose all bottom side, then you can use the terminal block. But looking at the components, I don't understand any of these limitations: 1) Why do I need to choose bottom-side installation in order to use a terminal block? The components all seem to fit, regardless of which side I choose. 2) Why do they all need to go on the same side of the board? I don't have any reason to distribute them randomly, but since they all seem to fit either way, I'm thinking there must be something going on which I don't quite understand. I'm not 100% sure on the specifics of how I'm going to use these boards yet, so I don't want to solder myself into any limitations. Also, are schematics available for eggtimer kits? This is my second one, and the second time I've found it would be helpful to have a schematic to consult during assembly.
