DC Motor + Stepper FeatherWing Add-on

DC Motor + Stepper FeatherWing Add-on info

DC Motor + Stepper Feather Wing lets you use 2 x bi-polar stepper motors or 4 x brushed DC motors (or 1 stepper and 2 DC motors). Feather Wing Add-ons can easily be connected on top or bottom of the Feather boards using Feather Stacking Headers or Feather Female Headers.

The original Adafruit Motor Shield Kit is one of the most beloved kits and that is why Adafruit decided to create one for the Feather platform and make it even smaller, lighter, and more portable. Instead of using a latch and the Arduino's PWM pins, a fully-dedicated PWM driver chip is used onboard. This chip handles all the motor and speed controls over I2C.

Since DC Motor + Stepper Feather Wing only uses the I2C (SDA & SCL pins), it works with any and all Feathers- ATmega32u4, ATSAM M0 or ESP8266-based. You can stack it with any other Feather Wing or with itself (just make sure you have each wing with a unique I2C address).

DC Motor + Stepper Feather Wing pack comes with an assembled & tested Feather Wing, terminal blocks & plain header. Some soldering is required to assemble the headers on. Stacking headers, Feather and motors are not included. You can use any DC or stepper motors that run from 4.5-13.5VDC and draw under 1.2A (3A peak) per coil.

There’s a great tutorial in the Adafruit Learn System for the bigger but similar Motor Shield with a lot of documentation and example code, so please check it out.

Please note that unlike the full sized shield, there are no servo connections on the Feather Wing (they wouldn’t fit). So if you need a bunch of servos, check out the 8-channel Servo Featherwing

DC Motor + Stepper Feather Wing Add-On - General Specifications

• 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
• Easy-to-use Arduino software library by Adafruit
