DVR 8825 vs l298 & l297
Hello everyone
left is A4988 and right is DRV8825
DRV8825 promises a max current of 2.8A peak and 1.5 per phase
you know these are really cheap and small drivers that even they do micro stepping!!
on the other hand the combination of l298 and l297 can be expensive if used in smd forexample l298p smd package
and they promise 2 Amps
yeah l297 doesn't have microstepping uless you use l298 alone and use a micro processor along with it for micro stepping
here is the circuit of l298 and l297 in l297 data sheet as you have noticed it has lots of components like shotcky Diodes, high watt, Rsenses
schematic
what is the diffrence between these stepper drivers that i'm not noticing
