Wired Breadboard / Protoboard

Product Description

This protoboard was suggested for use in our physical computing classes by a colleague. It is a copy of a “solderless breadboard”, hence the extremely creative name “wired breadboard”. It is wired just like a solderless breadboard, so you can transfer your project directly from your solderless breadboard to this PCB.

These are made of industry-standard FR4 (glass-fiber epoxy) with plated through holes and finished with ROHS compliant tin finish. For beginners, this is the most foolproof way to move a design from a solderless breadboard to a more permanent prototype.

For smaller projects, either size breadboard is easily and neatly cut with a pair of large tin-snips or jewelers saw.  A bandsaw will work too but the fiberglass is hard on the blade.
