A collection of protoboard designs, all ready-to-order via your favourite PCB manufacturer. Boards in the collection: - Breadboard-compatible - all with power rails on both sides as well as extra holes and pads for connecting power: - Small (15 rows of 2x5 points) - Medium (30 rows of 2x5 points) - Large (60 rows of 2x5 points) in two variants: a) with continuous power rails, b) with power rails split halfway - A stripboard with an exotic strip layout (to allow clever layouts with minimal amount of extra soldering) and power rails spanning the entire board. - Arduino UNO-compatible protoshield in two variants: - Plain (just a grind of holes) - With power rails running down the middle and two easy options of connecting power to VCC (either via pin jumpers on top or solder jumpers on bottom).
