How do I use the prototyping area on a SparkFun MicroSD Card shield?
This type of board, "pad per hole", has no pre-made interconnects. If you use thin enough wire sometimes you can push two pieces of wire into the same hole before you solder, say a resistor lead and another wire to connect to the next component. You can also solder an interconnect wire to the protruding leg of a DIP chip. You can make a buss for ground or 5v by assigning a whole row for that purpose, on the top side wire everything that needs to connect to that buss, and on the bottom side solder a straight piece of bare wire to all those wire ends in that row.
