So I am designing a pcb for my robot, and I would greatly appreciate some constructive criticism.
I have attached the eagle schematic and board file.
I use 2 arduino's because I have 2 I2C devices and their address cant be changed for some reason...
and I am using BTN7971B For my motor controller as I will be controlling 4 fairly high power motors
I have attached the circuit which I based the design on for the motor controller, and also I am using a lm2576 for 5v regulation for which
here is the original circuit: http://www.hobby-hour.com/electronics/lm2576-step-down-switching-regulator.php
basically If you wold have any advise/ tips on the layout/circuit please advise.
It's not finished, things like the pin outs to my sensor, but most of the main circuitry is there.
One thing I am sure I will need to change is all the small capacitors being replaced for a larger one, any suggestions on a
suitable value for those capacitors would be great.
So any advise or suggestions would be much appreciated
