Yikes! The DPI setting in import-bmp controls something much more important than the scaled image size: It controls the size of the “pixels” that your image is drawn with, which in turn affects the end file size and could have consequences for manufacturability.
600DPI equates to 1.6 mil lines. If you’re putting this in a silkscreen layer, well, chances are, the fab’s silkscreen printer is basically 200DPI. Your image may or may not show up, depending on the fab’s pre-processing process. This goes similarly with the soldermask layer (though the resolution is often higher).
The worst is if you try to put this on a copper layer. Each 1.6mil pixel is going to throw a “trace too small” warning in the fab’s DRC software.
The moral: Be nice to your fab, and scale the image outside of import-bmp, so it processes well at 200DPI or smaller.

Hideous color. ;)

Oh, in fact they make a separate product (the “PodSync”), that does exactly that, and they sell it for the same price. How odd.
Huh! I wonder why they wouldn’t just connect USB D+ and D- to the appropriate D+ and D- on the iPod connector.
It seems like that would be such a simple thing that would make the product SO much more useful!

Awesome! It’s like a Linx RXM-GPS-SR-B, but with Compass and accelerometer. Same footprint too, it looks like.
32mA typical at 3.3V and a max of 83mA.. Oh, and a good input voltage range.

What do you call this type of connector? I have a bunch of 28 pin LCDs with the flat ribbon cable, but no way to hook them up without buying a 28pin one of these..
No public wish lists :(
