I've been building circuits since 2007 so I know I shouldn't 'have' to ask this question but I don't know the answer so I have to ask the forum.
What diode should I use for a DC motor @12volts
and @20Khz PWM? On some projects I mix DC motors and servos at different voltages. Add to that a wireless module at yet another voltage.
I bought some optocouplers to isolate my Propellers until I figure out what I'm doing wrong. I have been experimenting with six to nine volts to power my motors but I want to scale up some of my projects to 12 or 24 volts.
Can I solve the problem with better diodes?
