    Best H-Bridge to run motors with Teensy 3.1

    Dear all,

    I am so new in robotics and I am supposed to build a robot arm with seven 12v DC motors to be controlled simultaneously by a Teensy 3.1. Now I am looking for a good motor driver. Do you have good suggestions for me? The limitation is the number of H-bridge I should use.
    I search through internet and tempted to buy these:

    I don't know if I buy two of these boards and mount them on breadboard, can I drive 7 motors all together by Teensy?

    Thank you so much.

    Those are not H-Bridges, the board connects motor Vin to Teensy Vin and the Teensy cannot handle 12 V. Not a good choice for 12 V. These might be better since they are H-bridges but you will have the same problem and these have a max Vin of 11 V. If you have to drive 12 V DC motors you will have to have a separate motor supply from the one that drives the Teensy.

    Thank you for your reply. I would like to power Teensy by USB from my laptop and I will have separate power supplier for my motors.
    Can I know your opinion about this product?

    I want to find an inexpensive small H-bridge to work well with Teensy.

    Thank you so much.

    Looks like it will work for your 12 V motors.
