Im kind of new to this stuff but haveing a great time learning and doing it.
The DRV8825 stepper motor controller has the following warning:
The DRV8825 carrier board uses low‐ ESR ceramic capacitor, which makes it susceptible to destructive LC voltage spikes, especially when using power leads longer than a few inches.
To protect the driver you can connect an electrolytic capacitor between VMOT and GND. Pololu suggests a
capacitor of 47μF or more (I show a 100 μF capacitor in the attached diagram).
Do I need this 100μF capacitor
if Buck Voltage Step down has this 220μF and is wired within 6 inches from the LM2596S Buck Step Down?
Better safe then sorry or over kill?
Thanks All for this Forum and the help you provide. Keep Safe
