I bought an Arduino motor driver L9110S, and the L9110 came. If you look at the circled part, it says B-2A instead of B-1B. Why is this like this?
Actually, as long as the operating voltage is correct and it works, it doesn't matter whether it's L9110, L9110S, or B-2A, but I'm worried that it won't work.
I will use 6v in that motor driver, and 2 DC motors.
I think I said something too vague, so I'll put the questions together...
1. Difference between L9110 and L9110S
2. When using two DC motors running at a voltage of 6v, is L9110 suitable/unsuitable?
3. Why is it called B-2A instead of B-1B and the difference between the two?
3-1. Is there any part that needs to be connected differently from the B-1B motor driver?

If you look at the pin names in the datasheet, the two input pins are IA and IB.
where I means input
It is natural for Chinese-made products to have many errors, so users should use them on their own.
B-IA, B-IB, GND, VCC, A-IA, A-IB
You can view them in this order.
//
The above driver module can drive 12V or less.
There is no problem in driving a 6V motor using a 6V supply.
You must drive a motor with a current consumption of 0.8A or less.

L9110S has the same name as the motor driver module.
L9110 is an internally used IC designation.
