Adafruit MotorShield v2.3 (Assembly Kit) - Motor/Stepper/Servo Shield for Arduino

• New version 2.3!
• 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.
• 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.
• Instead of using a latch and the Arduino's PWM pins, we have a fully-dedicated PWM driver chip onboard. This chip handles all the motor and speed controls over I2C. Only two pins (SDA & SCL) are required to drive the multiple motors, and since it's I2C you can also connect any other I2C devices or shields to the same pins. This also makes it drop-in compatible with any Arduino, such as the Uno, Due, Leonardo and Mega R3.
• As of 3/21/2014 we are * motor shields with the terminal blocks, and power jumper pre-soldered on. You'll still need to do a little soldering to put on the shield-headers (or stacking headers) but it should be even easier and faster to get started!

You will find the following items: 1 x Adafruit MotorShield v2.3 (kit) – Shield Arduino for motors, stepper motors and servos, 1 bridge 1 pin bar, 36 pins. The pencil bar still needs to be divided and welded in the intended places. Note: Please note that this product is a construction kit and welding work is required for commissioning. Adafruit Description: The original Adafruit Motorshield kit is one of our rather beloved kits, which means we are determined to make something even better. We have upgraded the shield kit to make the best way to easiest way to drive DC and Stepper motors. This shield will make quick work of your next robotics project! We kept the ability to drive up to 4 DC motors or 2 stepper motors, but we added many improvements: Instead of a L293D darlington driver, we have the TB6612 MOSFET driver: with 1.2A per Channel and 3A peak Current Capability. So it has low voltage drops across the motor so you can get more torque out of your batteries and there are built-in running diodes like well. Instead of using a latch and the Arduino's PWM pins, we have a full dedicated PWM driver chip onboard. This chip drives the entire engine and speed controllers via I2C. Only the two-pin pins (SDA and SCL) were required to drive the multiple motor, and therefore you can connect any other I2C devices or shields to the same pins. This makes it compatible with any Arduino, such as the Uno, Due, Leonardo and Mega R3. Fully stackable design: 5 address selection pins allow up to 32 stackable locks: 64 motors or 128 CC What could you do with the many steps? I have no idea but if you're arriving with something sending a photo because it's a glorious project. Lots of other little improvements such as a polarity protection FET on the power pins and a bit of protoyping area.
