DC Motor + Stepper FeatherWing Add-on For All Feather Boards

CAD model by Adafruit Industries, MIT

A Feather board without ambition is a Feather board without FeatherWings! This is the DC Motor + Stepper FeatherWing which will let you use 2 x bi-polar stepper motors or 4 x brushed DC motors (or 1 stepper and 2 DC motors).

Motor power +
External motor supply positive input. Adafruit Learn states to provide 5-12V DC power for driving the motors on the motor power pins.

GND

ground

Feather logic ground, required with 3.3V logic power.

0V logic reference

SDA

signal

I2C data line used for all control. Adafruit Learn states SDA is the right highlighted I2C pin near the mounting hole and has a 10K pullup to 3.3V.
