[openmulticopter] Analog and Digital power supply

[Heinrich Warmers]

Hello,
one LC element before the linear voltage regulator is good.
Pleas look for the sparkfun PCB for the idx500 they use a low noise
voltage regulator (with bypass capacitor).
I use one connection from analog to digital ground wiht an 1 Ohm
resistor to avoid coppeling common to the ADC.

Regads
