1468Re: Xbee , motor controller and control circuit
- Nov 1, 2008Separate PS are not a bad idea. RF for sure is going to send some
interferance. I would suggest a metal shield over the rf part.
Inductor and capacitor should be good, the motor part is going to have
also affect PS. Inductor or fuseable resistor, big capacitor and small
capacitor should do. for the logic - same practice and 100 - 150 nf
close to the MPU or under.
All module grounds should go separate to the point where PS is
connected and meet there. Same rule for 3 or 5V. 10=100MF are good as
boost for logic and RF, 100-150 nf for filter in parallel. Metal
shiels are good practice.
