hey im looking to try build a pcb for stepper control,
im using 8 steppers with a teensy 4.0,
i have so far built up most of the pcb but have started to worry im missing something.
i have a screenshot of the board in kicad https://imgur.com/a/rQrX4iQ
as you can see its not finished im just wokring on the basics to see how it looks,and thought id ask other before i continue down some hole.
so far my setup is
8x tmc stepper drivers-- all drivers are 3.3 compatable
bluetooth and hc12 adaptor for wireless control. 3.3 compatable
regulator for the teensy vin pin,
a couple of buttons and led to show its started up and thats about it.
8 x motors
i have added the needed caps to vmot and gnd as normal and added resistor to the ms1 pins to ground.
other than this is there anything else i should be doing?
its my first time im doing a pcb are my lines ok or should i have them set up differently,i have tried to make the input voltage go direct to motors and have made the stepper pin adaptors as short as possible,
i havent added any diodes on input or fuse's should i?
as at times i may be powered via battery>vin and i would still be using usb serial at times i should cut the vin trace to vusb?
my input voltage will either be a ac>dc 12volt input or it will be 14.8v4s2p lion pack connect via a bec to an xt60,if my bec brings down the voltage to 6v should i be fine to put that directly to the vin pin on teensy?or should i use my own regualtor still.
just looking for a little tip,thanks
