The Pololu Motoron M2T550 Dual I²C Motor Controller offers a compact solution for controlling two DC motors using an I²C interface. Multiple Motoron controllers can be connected to the same I²C bus, making it easy to expand a system with additional motors. The M2T550 supports motor supply voltages from 1.8 V to 22 V and can deliver continuous output currents up to 1.6 A per motor. Available with or without pre-soldered headers - select the required version before adding to your cart. The unsoldered version comes with a loose 16x1 header strip. The Motoron M2T550 and M2U550 controllers make it easy to control two bidirectional, brushed DC motors using an I²C or TTL serial (UART) interface, respectively. These compact (0.6″ × 0.8″) boards support motor supply voltages from 1.8 V to 22 V and can deliver continuous output currents up to 1.6 A per motor. Multiple Motoron controllers can be configured to work on a single I²C or serial bus, allowing independent control of many motors. Unlike most of our motor drivers, the Motoron does not require any PWM outputs or timers on your microcontroller. Instead, only a single I²C or UART interface is needed regardless of how many Motorons you connect. These Motoron controllers are available in several versions with different combinations of communication interfaces and connector options: * M2T550 (I²C) (this item): * headers soldered * headers included but not soldered in * M2U550 (TTL serial): * headers soldered * headers included but not soldered in For smaller single-channel alternatives, consider the Motoron M1T550 and M1U550. Connection Example Features * Two motor control channels allow for independent control of up to two bidirectional brushed DC motors per Motoron * Wide motor supply voltage range: 1.8 V to 22 V (absolute maximum) * Maximum output current per motor: 1.6 A continuous, 5 A peak for <1 second * Reverse-voltage protection on motor power supply (down to −20 V) * Logic voltage range: 3.0 V to 4.9 V (5V nominal not recommended) * Control interface: M2T550: I²C (up to 400 kHz) * Optional cyclic redundancy checking (CRC) * Configurable motion parameters: * Max acceleration/deceleration forward/reverse * Starting speed forward/reverse * Direction change delay forward/reverse * PWM frequency: eight options available from 1 kHz to 80 kHz * Command timeout feature stops motors if the Motoron stops receiving commands * Configurable automatic error response * Motor power supply (VIN) voltage measurement * Two status LEDs * Motor direction indicator LEDs * Error output for easier detection of error conditions * Motoron Arduino library simplifies using the Motoron with an Arduino or compatible controller * Motoron Python library simplifies using the Motoron with Python or MicroPython * Comprehensive user’s guide * Compact 0.6″ × 0.8″ size Specifications Channels 2 Model Motoron M2T550 Control interface I²C Minimum operating voltage 1.8 V Maximum operating voltage 22 V Continuous output current per channel 1.6A Peak output current per channel 5A Minimum logic voltage 3.0 V Maximum logic voltage 4.9 V Reverse voltage protection?
