Rich Grise said:In addition to the other suggestions, if at all possible, split the
two 6V busses right at the power supply - that way the power supply
filter will help keep the motor noise out of the GPS. Also, split
their return lines the same way.
A ferrite bead is just a little torus of ferrite that strings on the
power lead just like stringing beads on a string. It adds a little
inductance, and presents a high impedance to higher frequency noise.
But with only 70 mA, you might even use an ordinary RF choke - it
might make it easier to assemble, but only you can determine that.
This is how I have it laid out right now. Return line is a ground plane
that everything uses - should I be changing this? Thanks,
