1 | Board characteristics: |
2 | |
3 | - two layers, components only on front |
4 | - smallest components are 0402 and 0.5 mm pitch QFN |
5 | - the following component orientation markings are on the silk screen: |
6 | B1: circle near pin 1 |
7 | U1: triangle at the corner between pins 1 and 32 |

13 | atben-bom.csv Bill of materials |
14 | atben-pos.csv Automatic insertion file (front only) |
15 | atben-footprints.pdf Footprint reference drawings |

20 | Interpretation of files: |
21 | |
22 | - for all coordinates, the origin is the lower left corner of the board |
23 | - coordinates in atben-pos.csv are in inches |
24 | - rotation in atben-pos.csv is in degrees, counter-clockwise |
25 | - in the footprint reference drawings, footprints are shown in the 0 degree |
26 | orientation and with their center at the crosshairs |
