Making matrixboard fit into enclosures can be a bit tricky, so I decided to create some PCBs specially for common enclosures.

The first design is for a Hammond 1551GGY plastic box. It is a very compact enclosure ideal for small circuits containing only one or two ICs. I use them for Atari Paddle Connectors and console gamepad converters. It is designed for DIL ICs with two power rails down the middle and markings for an ATmega8/88/168/328. There is also a gap in the + power rail with an extension of the - rail for the AVR's GND pin to connect to.
