{"title":"Adafruit DC  Stepper Motor Bonnet for Raspberry Pi","handle":"adafruit-dc-stepper-motor-bonnet-for-raspberry-pi","url":"/products/adafruit-dc-stepper-motor-bonnet-for-raspberry-pi","description":"The Adafruit DC & Stepper Motor Bonnet drives up to 4 DC motors or 2 stepper motors from your Raspberry Pi, with full PWM speed control. It uses a dedicated PWM driver chip over I2C, so only two pins (SDA/SCL) are needed — leaving the rest free for other I2C devices or HATs.\n\nThe TB6612 MOSFET motor drivers provide 1.2A per channel (3A peak for ~20ms), a significant improvement over older L293D-based drivers. Built-in flyback diodes and a polarity-protection FET keep your Pi and Bonnet safe from wiring mistakes.\n\nKey Features\n\n\n4× H-Bridge Motor Drivers – TB6612 chipset, 1.2A per bridge with thermal shutdown and kickback protection\n\nUp to 4 DC Motors – Bi-directional with individual 8-bit PWM speed control\n\nUp to 2 Stepper Motors – Unipolar or bipolar, single/double coil, interleaved, or micro-stepping\n\n4.5–13.5V Motor Power – Polarity-protected 2-pin terminal block with jumper\n\nI2C Control – Dedicated PWM chip, sharable bus with other I2C devices\n\nStackable – Up to 32 Bonnets for controlling up to 128 DC motors or 64 steppers\n\nFully Assembled – Terminal blocks and 2×20 header pre-soldered, plug and play\n\n\nProgramming\n\nPython (pip-installable library with examples)\n\n\nCompatibility\n\nAny Raspberry Pi with 2×20 GPIO header (Pi Zero, A+, B+, Pi 2, Pi 3, Pi 4, Pi 5)\n\n\n\nImportant: Raspberry Pi, motors, and power supply are not included. A 5–12V DC power source is required for the motor power input.\n\n\nIdeal For\n\nRobotics projects with DC motors or stepper motors\nAutomated camera rigs and pan/tilt systems\nCNC and 3D printer motion control\n\n\nPackage Contents\n\n1× Adafruit DC & Stepper Motor Bonnet (fully assembled with terminal blocks and header)\n\n\n\nNote: Terminal block colour may vary (blue or black).\n","vendor":"Adafruit","product_type":"physical","in_stock":true,"options":[],"variants":[{"id":5076,"title":"Default Title","sku":"AF-4280","price":43.89,"on_sale":false,"in_stock":true,"available_quantity":1,"option1":"Default Title"}]}
