3.3V and 5V logic level on MD30C

Hello,

Could someone please clarify if anything needs to be done to switch between 3.3V and 5V level logic for the MD30C controller? I am interested in driving the MD30C 30A bi-directection motor controller via PWM for speed control. I was hoping to use a raspberry pi which would produce max pwm of 3.3V but I didn’t see any jumpers to make the change or choose voltages.

Hi,

The MD30C will work with both 3.3V and 5V logic levels without the need to configure it. The logic input high level of this controller is 3V to 5.5V and low level is 0 to 0.5V.

Regards,
