Power supply to L293D motor driver
The maximum current you can draw from the 5V pin is around 400 mA, or 900 mA, when the Arduino is powered by an external power adapter. The maximum current sourced or sinked by each driver input pin (xA) is 100 μA, and by enable pins (EN), it is 10μA, which is well within the limit of the Arduino digital pins, 40mA ( not 50 mA!).
