I am working on a low power device.
One can save power in hibernation by changing the LM1117 voltage regulator on the FEZ Mini board to a better one, it has a Quiescent Current on typ. 5 mA. This prevents one from reaching the 200 uA which the USBizi100 can do in hibernation. It should be changed for a rev 1.4 of FEZ Mini, some LDO’s has a Quiescent Current on a few uA.
Next, how to clock down/up the USBizi100 from .Net?
