Adafruit Perma-Proto Quarter-sized Breadboard PCB
When people build prototypes they usually start with a solderless breadboard and then transfer the parts to a more permanent PCB. Adafruit decided 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 realised it! Adafruit 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 white silkscreen, and the same markings you are 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. The drill holes are 1.2mm diameter, 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.
