I want to make a car, use the driver module, just have a piece of ULN2003 on hand, just think about whether you can use this chip to drive, check the DATASHEET, the current of each port is 500mA, I use the two ports in parallel Do a mouth control 1 motor, a total of 4 ports control 2 motors, the battery uses two 3.7 lithium batteries, do not know if this chip can work very well?
 

the current of each port is 500mA
You apparently stopped reading the datasheet at the second page. There's also a diagram "Allowable collector current as a function of duty cycle". Maximum DC current with 4 ports in use is e.g. 300 mA per port.
 

Aside from the limit FvM mentions, that device cannot 'drive' anything. It is a current sink only but you can use it in the negative side of your motors if you supply their positive sides from the batteries.
