Capacitors on PCB

Hi,
which capacitor should be used on a PCB with MPU6050 gyroscope and accelerometer module and should I use some capacitor with L298N motor driver, when it is on the PCB, but the connections are external?

Are all of these on the same PCB as a custom circuit or is it individual boards. Are they on the same power supply or batteries. A lot more information is need in order to supply an informed answer.

This is a link to the PCB layout, Arduino, NRF24L01, MPU6050 and servo which will be connected to the 3 pins oon the top are powered with one battery and L298N with other battery.
