Hello and good day everyone.

I bought MDD10A for building a linorobot. It has a PWM and a DIR (for reverse direction) inputs. I thought I could reuse L298n wiring by simply ignore input 1 for left motor and use input 2 for reversing the motor. I was able to use teleop to transmit pwm signal but both input 1 and input 2 were HIGH at the same time. Which made switching between forward and reverse impossible. Any solution?

Hi,

For 2wd use Motor A out 1 and Motor B out 4 leaving out2 and out 3 unassigned

Use PWM pins for both motors

I have tested MDD10A, it can be use as linorobot motor driver using L298n setup . Thank you.
