- modules/usb_a_plug_smt.fpd: enlarged hole for positioning pins from 1.1 mm to 1.15 mm - atusb/usb.sch, atusb/atusb.cmp, atusb/atusb.brd: removed trailing space from CON1's value - atusb/atusb.sch, atusb/usb.sch, atusb/atrf.sch: schematics title still said AT86RF230, not 231 - atusb/README-SMT: corrected a typo - atusb/README-PCB: specified the tolerance of the hole for the positioning pins of the USB connector - atusb/README-PCB: added the 16-17 mm hole for the USB connector to the specification - atusb/: bumped all version numbers to 20110330

Board characteristics:
|
|
|
|
- stacking: 2 layers, solder mask on front and back, silk screen on front
|
|
- board material: FR4, thickness 0.8 mm (1/32"), 1 oz copper
|
|
- surface finish: TBD, ENIG is preferred
|
|
- via holes: diameter is nominally 10 mil, but any size <= 15 mil can be used
|
|
- ground via of the antenna: hole diameter is nominally 8 mil, but any size
|
|
<= 15 mil can be used
|
|
- mechanical tolerances: <= +/- 0.1 mm on all sides
|
|
- the holes for the positioning pins of the USB connector have a nominal
|
|
diameter of 1.15 mm. The minimum finished hole size must be 1.10 mm,
|
|
maximum 1.25 mm.
|
|
|
|
|
|
Hole for the USB connector:
|
|
|
|
The USB connector extends below (!) the surface of the PCB. For SMT, a
|
|
16-17 mm hole must be left next to the PCB's edge:
|
|
|
|
<-17mm->

Interpretation of files:
|
|
|
|
- for all coordinates, the origin is the lower left corner of the board
|
|
- do not print component values on silk screen
|
|
- the center (!) of the board edge line marks the true board edge, e.g.,
|
|
|
|
Edge line (5 mil)
