RasPiO duino with ZIF socket.

I backed the RasPiO duino kickstarter, I finally found an opportunity to solder together one of my boards last night.

I used a ZIF socket instead of the standard chip socket so I had to make a few modifications to the layout (most of which could have been avoided by using the optional surface mount components instead of through-hole).

I mounted the ZIF socket upside down so that it remains completely within the footprint of the Raspberry Pi.

R1 would have obstructed the ZIF socket, so I mounted it on the bottom of the board.

C3 was also under the ZIF socket, I left a bit of length on its legs and pushed it flat.
The resonator was very close to the side of the ZIF socket, a jaunty angle saved the day there.
The LED was completely obstructed, two very short links to the handy prototyping area (directly below) solved that issue.

    One trick I have used in the past for ZIF sockets is to put them on top of a stack of regular sockets to lift them clear of obstructions.

  2. that’s a nice trick. In this case the LED and capacitor would still have been an issue but it could have saved a few problems.

    All told it wasn’t to hard to do, especially once I’d changed the soldering iron tip to a nice fine size.
