We found 1 Reddit mentions of Adafruit Motor/Stepper/Servo Shield for Arduino v2.3 Kit. Here are the top ones.
or
- 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 shipping 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!

Not located anywhere near the PNW but can answer some safety questions.
As long as you never work on live circuitry and connect + to + and - to - you should be safe (kind of an obvious thing to say about electronics as it’s true for most cases). And with the voltages you’re most likely working with (3V-12V) you should be safe even if you do mess up (and the voltages and currents you’re working with is where it’s important to make the distinction between safe to mess up and NOT safe to mess up).
The most damage you will do is short something and break the arduino or other circuitry you’re working with. A lot of times genuine arduinos will have short protection and be able to turn back on.
I would suggest using a different type of motor controller though such as a shield that fits on top of the arduino.
Maybe this one (cheaper) or this one (better)
PM me with any questions if you’d like and I’ll try to answer them.
