Overview

To go along with our Sick of Beige cases we started using standard PCBs. There are two versions of varying sizes. One is a rectangle with a Golden Ratio between it's length and with, while the other is a square. All the PCBs have 4 mounting holes in each corner which are not connected to any copper on the PCB.

Hardware

Hole dimensions and locations

Holes are located in the 4 corners exactly 4mm from the closest vertical, and horizontal edge. They are 3.2mm in diameter.

Cooper keep-out area

Around each hole there is a cooper keep-out area approximately 5mm from the center of the hole. In this area no traces, or ground fills are aplicable, to avoid contact with metallic standoffs,and screws.

Component placement keep-off area

No component may be placed 1.7mm from an edge of the board. this is for posible future cases that hold the PCB by the edges

Board's round corners

Each corner of the board is rounded with a 4mm radius arc.

Reference points and lines

Runing through the exact middle, both lengthwise, and lengthwise, is a reference line. Also added are two reference point for USB mini-B jack, 5.25mm for the left and right edges.
