Key Features
- Quarter-sized breadboard (the PCB has 17 rows)
- 4-hole pad design
- 1.2mm diameter drill holes - thru-plated for strength
- 1.8" x 2.0" (46mm x 55mm), 0.063" thick FR4
Adafruit put a PermaProto quarter-sized proto board in a blender with a Pi Cobbler and out emerged this very tasty confection - the PermaProto for Pi! It has the Cobbler baked right in. Simply solder the 2x13 pin header in and you get all the labeled breakouts with tons of prototyping space, power rails, mounting holes and that gorgeous silk.
This proto-board is the PCB you always wish you had, but never realized it! Adafruit took the basic layout of a quarter-sized breadboard (the PCB has 17 rows) and turned that into a beautiful PCB. The top side has a white silkscreen, and the same markings you're familiar with, to make transferring components easy. The bottom has a 4-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 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 tons of mounting holes so you can attach the PCB to your project box.
