How to directly solder wires to protoshield to connect them to Arduino pins I bought an assembled Arduino Uno protoshield version 5, similar to this:



I bought it because I would like to solder wires from Arduino IOs, and I was quite disappointed with the impossibility to do so, since the solder points are already taken by the female headers, which are not connected to anything (there are not tracks coming from then to other islands, which I find quite dumb).

I am considering to remove (by desoldering) the headers, so I can access the holes for soldering wires (instead of plugging them to headers), but before doing so, I ask:


  Is there a good way to solder wires so they are electrically connected to the Arduino IO pins?
For the signals, get some AWG30 wire and solder them underneath to the female header pads. For power, get some AWG22 or AWG24 wire and solder them to the top of the male header pads.
