Board characteristics:
|
|
|
|
- two layers, components only on front
|
|
- smallest components are 0402 and 0.5 mm pitch QFN
|
|
- one through-hole component: USB connector CON1
|
|
- the following orientation markings are on the silk screen:
|
|
B1: circle near pin 1
|
|
D1: plus sign at the anode
|
|
U1, U2: triangle at the corner between pins 1 and 32

Interpretation of files:
|
|
|
|
- for all coordinates, the origin is the lower left corner of the board
|
|
- coordinates in atusb-pos.csv are in inches
|
|
- rotation in atusb-pos.csv is in degrees, counter-clockwise
