This proto-board is the PCB you always wish you had, but never realized it! Adafruit took the basic layout of a full-sized breadboard (the PCB has 60 rows instead of 63 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 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 1.2mm diameter drill holes allow for parts with big leads to 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 three mounting holes so you can attach the PCB to your project box.
