Im using 3 servo SG90 that connected to raspberry pi for the data only, i give separate power supply for them.

2 servo Mg90

And 1 servo MG966R who have 7v input voltage.

4 pins to the motor driver LN 298 to control the movement of the wheels.

4 pins for the relay 4channels (to control electronics stuff with voice command)

7 pins for all servo.

So total pin that im using is 15. Not including ground pins
