The board is 4x1.8". Each block is 1/5" (2.54mm). Copper is red, components green. Seen from back, copper side. Solder dots and lanes should be as big as possible, naturally without overlapping. Copper should not go all the way out to the board sides/edge. Drill holes 1 mm, except the 2 mounting/center holes that should be 3 mm. The rest i.e. board thickness, etc. should just be cheapest standard.
