|---|---|
| 1 | Board characteristics: |
| 2 | |
| 3 | - two layers, components only on front |
| 4 | - smallest components are 0402 and 0.5 mm pitch QFN |
| 5 | - one through-hole component: USB connector CON1 |
| 6 | - the following component orientation markings are on the silk screen: |
| 7 | B1: circle near pin 1 |
| 8 | D1: plus sign at the anode |
| 9 | U1, U2: triangle at the corner between pins 1 and 32 |

| 14 | atusb-front.png Illustration of the PCB's front side (with silk screen) |
| 15 | atusb-bom.csv Bill of materials |
| 16 | atusb-pos.csv Automatic insertion file (front only) |
| 17 | atusb-footprints.pdf Footprint reference drawings |
| 18 | |
| 19 | The PCB design files (Gerbers, etc.) are in a separate archive, atusb-pcb-* |

| 22 | Interpretation of files: |
| 23 | |
| 24 | - for all coordinates, the origin is the lower left corner of the board |
| 25 | - coordinates in atusb-pos.csv are in inches |
| 26 | - rotation in atusb-pos.csv is in degrees, counter-clockwise |
| 27 | - in the footprint reference drawings, footprints are shown in the 0 degree |
| 28 | orientation and with their center at the crosshairs |
