PCA9685 + TB6612 DC Motor + Stepper Motor Driver Board

Description:

This is the DC Motor + Stepper motor driver board which will let you use 2 x bi-polar stepper motors or 4 x brushed DC motors (or 1 stepper and 2 DC motors).

Since this only uses the I2C (SDA & SCL pins), it works with any board - ATmega32u4, ATSAM M0 or ESP8266-based. You can stack it with any other board or with itself (just make sure you have each wing with a unique I2C address).

Motor Specs:

• 4 full H-Bridges: the TB6612 chipset provides 1.2A per bridge 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 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.
• Download the easy-to-use Arduino software library, check out the examples and you're ready to go!

You can use any DC or stepper motors that run from 4.5-13.5VDC and draw under 1.2A per coil.
