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). It features a fully-dedicated PWM driver chip that handles all the motor and speed controls over I2C.
Since the FeatherWing only uses the I2C (SDA & SCL pins), it works with any controller board with I2C interface.
- 4 full H-Bridges: the TB6612 chipset provides with thermal shutdown protection, internal kickback protection diodes. Can run motors on 4.5VDC to 13.5VDC.
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 64 steppers or 128 DC motors!
Comes with an assembled & tested FeatherWing, terminal blocks & plain header. Some soldering is required to assemble the headers on.
Dimensions: 50.8mm x 22.9mm x 1.6mm
