Need the perfect shield

Hi!

I require your help regarding a problem I’m encountering.

I need to control 4 servo and 2 x 9v dc motor:

using arduino uno R3 + external power supply:

Software concerned:

i have found a app to control the 4 servo via bluetooth and it work great but i need to add 2 dc motor for the tank part so i need to know the best shield compatible with arduino r3 out there:

Additional information:

Thank you so much in advance for your help!

Are you looking to control the DC motors through the app too ?

Do you have the specifications for these motors ? Before choosing a motor controller you need to know at least the nominal voltage and the current these motor will draw under load.

With an L298N H bridge of this type, it should be enough:
