Thank you for your answer. I checked again the solder on the pin PWM pin (and on other pins) using a multimeter, it is correct, 4.89 V.
I connected the power supply 19 V (I checked the power supply, it is working) to VIN and GND, I measured the voltage:
When I connected 5V (arduino) to SLP pin:
Each time the voltage on OUT A and OUT B pins is 0.0 V.
What do you think about it? Is the driver broken?
