I’m making a system which is using Arduino & Dual MC33926 Motor Driver Carrier or RPi3 & Dual MC33926 Motor Driver Carrier to control two motors.
But no matter which system I use, it’s not working. After I check everything, I found that my voltage of Vin is wrong.
Normally, voltage of Vin pin which connect to Power Supply should be as same as the Vin pin near VDD, right? However, no matter my Power Supply Vin get what Voltage, the Vin pin near VDD always get 0.44V.
Can anyone help me?
BTW, I must apologize for my poor grammar, I hope someone can understand what I’m talking about.
I am sorry you are getting that behavior on your dual MC33926 carrier. Was the driver ever working for you? Can you post pictures that clearly show your connections and soldering joints? What voltages were you supplying to the large VIN pin?
