I have problem with Pololu G2 High-Power 24v21. There is no voltage at the OUT A and OUT B. I showed in the picture how I connected it. .
I also tried:
a) connect 5V to SLP
b) connect Power Supply DC 19 V
c) connect only DIR pin, without PWM
d) connect VIN and GND to Arduino (5V)
but it did not help.
I have read the specification and forum. I checked the solder pins. I checked the voltage of Arduino, it is correct (4.89V). I don’t know if the driver has an LED, but I do not see any light. I was careful when measuring voltage the 3v3 pin, I did not touch the VM pin (I think the touch is not possible, I soldered pin header and inserted the cables).
What do I do wrong?
