Sewable Arduino Interface

Step 2 Preparing materials

Cut your perfboard and headers into following pieces (see sketch for details):

Perfboard
One: 5 x 6 holes
One: 5 x 15 holes
Two: 5 x 9 holes

Male headers
Two: 6 pin rows
Two: 8 pin rows

Female headers
Two: 3 pin rows

!!! Make sure to divide the 5 x 6 hole piece of perfboard into two disconnected sections 3 x 5 holes each. See picture for details.

File all the edges of the perfboards to that they are rounded and not sharp. This is to prevent the edges from rubbing and tearing at the conductive thread that will later be stitched to the edge holes.

The perfboard pieces can also be downsized, if you only plan on connecting only from one side. I also include two rows of holes on each side of the headers for extra space, which also makes sewing-to easier, but one row of holes to one or either side would also work, and make things smaller. I also include an extra row of holes to each side of each perfboard to sew them in place with regular thread. This takes strain off the conductive thread connections&. but can also be dismissed for downsizing.
