I bought a bts7960 and connected it to a battery. If I measure the voltage of the battery with a voltmeter and the battery is not connected to the bts7960, I measure 7.88 volts.
If I try to measure the input voltage of the bts7960, I measure 2. Something volts. Why is the input voltage lower than the battery voltage?

Here is a schematic.

You should not be Powering this Chip until it is permanently installed in a Circuit.
If your lucky, it's not damaged.
This Chip requires Micro-Computer Control, before it will do anything.

Are you sure that you know how to use this Chip, and what it is supposed to do ?

I was trying to get the bts7960 to turn on an electric motor, and it was connected to a arduino uno. I ran a program that was suppose to turn the motor for 10 seconds several times and the motor wouldn't turn on. I was just trying to make sure the circuit is working.

Here is a drawing of the setup
IMG_20210622_155947.jpg

Pin 5 of arduino uno is connected to RPWM of bts7960
and pin 6 of arduino uno is connected to LPWM of bts7960. 5 volt pin is connected to positive terminal of the breadboard. The 5 volt pin is not an output/input pin. Gound pin of the arduino uno is connected to the negative terminal of the breadboard. The L_EN, R_EN, and Vcc pin of bts7960 is connected to the positive terminal of the breadboard. So what is wrong with the setup?

Void loop {
pinMode( 5, OUTPUT );
pinMode( 6, OUTPUT );

analogWrite( 5, 200);
analogWrite( 6, 0);
delay( 5000 );
analogWrite( 5, 0);
analogWrite( 6, 0);
