The original L293D Motorshield kit is one of our most beloved kits, We kept the ability to drive up to 4 DC motors or 2 stepper motors, but added many improvements:
Instead of a L293D darlington driver, we now have the TB6612 MOSFET driver: with 1.2A per channel and 3A peak current capability. It also has much lower voltage drops across the motor so you get more torque out of your batteries, and there are built-in flyback diodes as well.
Completely stackable design: 5 address-select pins means up to 32 stackable shields: that's 64 steppers or 128 DC motors! What on earth could you do with that many steppers? I have no idea but if you come up with something send us a photo because that would be a pretty glorious project.

For A rduino interface is fully compatible with the extension. and communication through 2c and address can be modified. It can take two motors with direct WM drive output. Up to four DC brush motors or two four-wire stepper motors can be connected. Using TB6612FNG motor driver chip, 1.2A drive capability, 3.2A peak,peak L298N module. We now have the TB6612 MOSFET driver: 1.2A and 3A peak current per channel. it also has a lower motor voltage drop, so more torque can be obtained from the battery. Instead of using latches and for Arduinos PWM pins, we have a fully dedicated pWM driver on the chip. The chip handles all the motor and speed control on the 2C. Only two pins (SDA and SCL) are needed to drive multiple motors. Stackable design.
