NEW PRODUCT – Adafruit Perma-Proto Quarter-sized Breadboard PCB – 3 Pack!

Window-34

NEW PRODUCT – Adafruit Perma-Proto Quarter-sized Breadboard PCB – 3 Pack! Customers have asked us to carry basic perf-board, but we never liked the look of most basic perf: its always crummy quality, with pads that flake off and no labeling. Then we thought about how people actually prototype – usually starting with a solderless breadboard and then transferring the parts to a more permanent PCB. That’s when we realized what people would really like is a proto board that makes it easy!

This proto-board is the PCB you always wish you had, but never realized it! We took the basic layout of a quarter-sized breadboard (basically, a ‘tiny’ breadboard plus power rails) and turned that into a beautiful PCB. The top side has a while silkscreen, and the same markings you’re familiar with, to make transferring components easy. The bottom has the 5-hole pad design that matches a classic breadboard, with 4 power bus lines on the sides, and no mask so you can easily cut traces when necessary. We used 1.2mm diameter drill holes so even parts with big leads will fit. All holes are thru-plated for strength – these wont peel off with rework. The finish is a gold plate – you won’t get oxidation like with bare copper perf! There are also two mounting holes so you can attach the PCB to your project box.

These are so handy, we decided to put them in a pack of 3. Once you use a Perma-Proto board, you’ll never go back!

  1. those are great!

    may I offer a suggestion? for high current projects, the thin traces between the pads are a bit limiting, can you upsize the traces between the pads to match the bus bars?

  2. @mike! we specifically decided to keep the traces between the pads thin and have no solder mask so that you can easily cut them. it’s the product description.

    “The bottom has the 5-hole pad design that matches a classic breadboard, with 4 power bus lines on the sides, and no mask so you can easily cut traces when necessary”

    they’re 16 mil, which is pretty good 🙂
