Powering L298N Module using Arduino Uno 5V Pin

Other Hardware General Electronics
1

Hi all. I have only recently started using and Arduino Uno and I am also new to electronics. I am trying to make a Maze Solving car using an Arduino Uno, L298N Module and a couple of HC-SR04 Sensors.

I know how to connect the HC-SR04s but I am having trouble with the L298N. I want to know if it is possible to power it with the 5V pin from the Arduino Uno. I am reading somewhere that it's Drive Voltage is 5V-35V, but somewhere else people are saying 6V-35V.

I am really stuck because of this. I have to make this project for school and the deadline is close so any help will really be appreciated. TIA

You didn't say what motor or motors you're using but the answer will still be, no not a chance!

The old tech L298N drops around 2V-4V so trying to run it off 5V may only leave 1V for the motor(s). Also the Arduino 5V pin cannot supply nearly enough current for motors. You really need to use at least 9V and not a little rectangular 9V battery (6 x AA cells is usually good).
