DC Motor And Stepper FeatherWing Add-on Board Unveiled By Adafruit

FeatherWing Add-on Board
Adafruit has unveiled a new addition to their range of add-on boards with the launch of the new DC Motorand Stepper FeatherWing add-on board, which has been specifically designed for all Feather Boards.
The FeatherWing will allow you to add 2 x bi-polar stepper motors or 4 x brushed DC motorx or 1 stepper and 2 DC motors. Also using the Adafruit Feather Stacking Headers or Feather Female Headers you can connect the new FeatherWing add-on board either on top or on the bottom of your Feather board
The original Adafruit Motorshield Kit is one of our most beloved kits, which is why we decided to squish it all together on a FeatherWing to make something even smaller, lighter, and more portable! 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. You can use this FeatherWing with any of our Feather boards: ATmega32u4, ATSAMD M0 or ESP8266-based.
FeatherWing Add-on Board
Motor FeatherWing Specs:
– 4 full H-Bridges: the TB6612 chipset provides 1.2A per bridge (3A peak) with thermal shutdown protection, internal kickback protection diodes. Can run motors on 4.5VDC to 13.5VDC.
– Up to 4 bi-directional DC motors with individual 12-bit speed selection (so, about 0.02% resolution)
– Up to 2 stepper motors (unipolar or bipolar) with single coil, double coil, interleaved or micro-stepping.
– Motors automatically disabled on power-up
– Big 3.5mm terminal block connectors to easily hook up wires (18-26AWG) and power
– Polarity protected 2-pin terminal block and jumper to connect external power, for separate logic/motor supplies
– Completely stackable design: 5 address-select jumper pads means up to 32 stackable wings: that’s 64steppers 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.
– Download the easy-to-use Arduino software library, check out the examples and you’re ready to go!
