Has anyone tried one of these motor controllers? If so how did you wire it up? I've blown up two of the L298N's.

Edit: I wired it in with 5V to the VCC, R_EN, and L_EN. And ground of course to the logic side of it. Then used the L_PWM and R_PWM pins from the arudino pins. That seems to work. But the problem I have is if I power things up with the 5v logic side first, then the motor power, everything is fine. If I have motor power (12v) connected first, every time the arduino "gets lost" trying to home. Turn off voltage to the motor controller and it will immediately state home. Turn the power back on to the motor and all is fine. Leave the 5V supply up and running and the motor supply up and running and simply hit the reset on the arduino and it gets lost again trying to home. Turn power off to motor, instant home.

These controllers seem to work much better though with the robot arm. I've been able to run high voltages without any sort of issue unlike the L298N's.
