I’ve got a slight concern when it comes to my design - It incorporates a GPS module, RAZOR IMU, and two 6amp/7v2 Motors, together with a pololu dual motor controller.
The GPS module needs under 50microvolt fluctuations on its power line to function reliably, and I can confirm that this isn’t just a theoretical thing - Without at least 3 capacitors on a computer usb power line it is impossible to get a lock.
The IMU relays on magnetometres - Not something I’d put next to a Motor if my life depended on it.
How would I work out a reasonable distance to place those components at? With the GPS, too close to the motors and I will not get a lock altogether, however I would assume precision is directly proportional to the distance squared, so I need to work out the optimal point. This is taking into consideration that I have tight space constraints, and really, the closer I can put it and still be confident with the data the better.
Any advice on how to deal with this?
