Adafruit DC & Stepper Motor Bonnet for Your Pi Now Available
A new Raspberry Pi stepper motor and DC bonnet has being designed by Adafruit and is now available to purchase from their online store priced at $22.50.
The Raspberry Pi bonnet can drive up to 4 DC or 2 stepper motors with full PWM speed control offering a great solution for robotics, DIY milling machines or 3D printers.
Specifications include :
- 4 H-Bridges: 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 8-bit speed selection (so, about 0.5% resolution)
- Up to 2 stepper motors (unipolar or bipolar) with single coil, double coil, interleaved or micro-stepping.
- Big terminal block connectors to easily hook up wires (18-26AWG) and power
- Polarity protected 2-pin terminal block and jumper to connect external 5-12VDC power
- Works best with Raspberry Pi model Zero, A+, B+, or Pi 2, Pi 3, etc but can be used with a model A or B if you purchase a 2×13 stacking header
- Install the easy-to-use Python library, check out the examples and you’re ready to go!
The Raspberry Pi stepper motor and DC bonnet supports all Raspberry Pi computers with a 2×20 connection port and you can even stack multiple motor bonnets enabling you to use up to 32 for controlling up to 64 stepper motors or 128 DC motors in a single project.
