Not all Arduino users design their own shields, but if you do, you certainly want to be able to use surface mount parts. Our through hole Arduino shields have our signature offset grids which makes better use of the space on our boards and give you more flexibility. Our boards also have a ground plane and pre-routed traces to reduce the need for jumpers. We then bundle our SMT to DIP adapters with the Arduino boards to make SOIC, QFP, QFN/DFN part of your workable solution. Schmartboard is the only Arduino solution for the real designers who do not want any limitations in their Arduino projects.
