Eagle Schematics for Breakout Board / device for ISM300F2
The following files were created based on Upu's original board for the ISM300F2 chip:
ism300f2_breakout.zip
Expect to see a “Board and schematic are not consistent” error when you open this. Ignore it, the board works fine.
The number of pins were reduced from 8 to 5, since several of the busses are now connected. The 5th pin, the ON/OFF pin, is optional, and the board will work even if this pin is not soldered to anything. It was left open for anyone with a desire to control the power consumption of the chip to be able to use it, per Inventek's guide.
Here's an image of the board as it appears in Eagle:
