{"title":"4 Channel I2C Motor Shield-V1.1","handle":"4-channel-i2c-motor-shield-v1-1","url":"/products/4-channel-i2c-motor-shield-v1-1","description":"This motor shield uses dual TB6612 MOSFET drivers and a PCA9685PW I2C PWM controller to drive up to 4 DC motors or 2 stepper motors from an Arduino or compatible board. All motor control and speed management is handled via the I2C bus, freeing up digital pins for other uses.\n\nThe stackable design with 5 address-select pins allows up to 32 shields to be stacked, controlling up to 128 DC motors or 64 stepper motors. It also includes 2 servo connections tied to the Arduino's dedicated timer for high-resolution control.\n\nKey Features\n\n\nI2C Control – PCA9685PW PWM driver handles all motor control on the I2C bus\n\nTB6612 Drivers – 1.2A per channel continuous (3A peak for ~20ms), with built-in thermal shutdown and flyback diodes\n\n4 DC Motors or 2 Steppers – Bi-directional DC with 8-bit speed control, or unipolar/bipolar steppers with multiple stepping modes\n\n2 Servo Outputs – Connected to Arduino's dedicated timer\n\nStackable – Up to 32 shields (5 address-select pins) for massive motor arrays\n\nSafe Power-Up – Motors automatically disabled on power-up\n\nTerminal Block Connectors – Easy wire hookup (18–26 AWG)\n\n\nSpecifications\n\n\nMotor Driver – TB6612\n\nPWM Controller – PCA9685PW\n\nChip Working Voltage – 5V\n\nMotor Voltage Range – 4.5–13.5V DC\n\nCurrent per Channel – 1.2A continuous, 3A peak (~20ms)\n\nSpeed Resolution – 8-bit (~0.5%)\n\nInterface – I2C (compatible with other I2C devices on the same bus)\n\nDimensions – 70 × 53 × 23mm\n\nWeight – 27g\n\n\nStepper Motor Modes\n\nSingle coil\nDouble coil\nInterleaved\nMicro-stepping\n\n\nIdeal For\n\nRobotics projects with multiple motors\nCNC and motion control\nArduino motor control applications\nLarge-scale motor arrays (stackable)\n\n\nPackage Contents\n\n1× 4-channel I2C motor shield V1.1\n\n\nResources\n\nEagle PCB Files\n","vendor":"Elecrow","product_type":"physical","in_stock":true,"options":[],"variants":[{"id":4057,"title":"Default Title","sku":"EC-ARS27361T","price":23.34,"compare_at_price":0.0,"on_sale":false,"in_stock":true,"available_quantity":104,"option1":"Default Title"}]}
