Protoboard is a great way to try out circuits before deciding to get PCBs made, or as a way to quickly produce a project that’s on a deadline. Classic protoboard is just a big matrix of holes without any connections – you have to make all the connections between nodes with wires, which can get messy really quickly and make debugging a pain. The Protomatrix routable perma-breadboard can connect all 160 rows into 30 different nets, simply by bridging pads at the edge of the board.
Each column on either side of the board is commoned together. Then each row of the tiny pads are not only commoned, but also attached the same row on the opposite side of the breadboard! This way, you can quickly and neatly route signals around the board without using any wires. Not only does this result in a much neater-looking end product, it can also make debugging much easier, as it’s visually apparent which nodes are connected together. You can also easily disconnect nets by using solder braid to remove the solder bridges connecting rows and columns.
Of course, this design is more expensive than regular protoboard, but these are great to have on hand in case you need to quickly prototype something. Having the connections be soldered also increases durability, and the neat look makes user-exposed circuits more appealing.
