Each GPIO pins can draw/sink 4mA and maximum I/O voltage is 3.3V.
3.3V power rail can draw up to 300mA.
5.0V power rail can draw up to 700mA.

Which devices will be connected to the 40pin GPIO header?

Right now i'm using this:https://www.mpja.com/Stepper-and-DC-Mot ... 4652%20MP/ dc motor driver to co0ntrol the two dc motors for robot wheel. But latter this: https://himalayansolution.com/product/7 ... ver-module one will be used.

You need an external PSU for the driver board and motors.
And you probably need a couple of level shifters for 3.3V to 5V(TTL) level translation.

Are you connecting a DC motor with PWM control? or stepper?
