  • Features reverse-voltage protection on the motor power supply
  • Compatible with Arduino or Python/MicroPython

The Motoron M2U550 Dual Serial DC Motor Controller is a compact and efficient solution for controlling two DC motors via a UART interface. This device allows for the connection of multiple Motoron controllers to the same serial bus, thereby facilitating the expansion of a system with additional motors. The M2U550 is designed to support motor supply voltages ranging from 1.8 V to 22 V and is capable of delivering continuous output currents of up to 1.6 A per motor. This particular model comes with header pins included, although they are not pre-soldered.

The Motoron M2T550 and M2U550 controllers are designed to facilitate the control of two bidirectional, brushed DC motors using an I²C or TTL serial (UART) interface. These compact controllers, measuring just 0.6 x 0.8 inches, support a wide range of motor supply voltages and can deliver continuous output currents of up to 1.6 A per motor. The unique feature of these controllers is that they can be configured to work on a single I²C or serial bus, thereby allowing for the independent control of multiple motors. Unlike many motor drivers, the Motoron controllers do not require any PWM outputs or timers on the microcontroller. Instead, they only require a single I²C or UART interface, regardless of the number of Motoron controllers connected.

The M2U550 model features a non-inverted TTL serial (UART) interface. This version comes with a 1x16 breakaway male header included, although it is not pre-soldered.

The Motoron controllers come with a host of features and specifications. They include two motor control channels for independent control of up to two bidirectional brushed DC motors per Motoron, a wide motor supply voltage range, and a maximum output current per motor of 1.6 A continuous. They also feature reverse-voltage protection on the motor power supply, a logic voltage range of 3.0 V to 4.9 V, and a control interface with optional cyclic redundancy checking (CRC). Other features include configurable motion parameters, a command timeout feature that 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, and an error output for easier detection of error conditions. The Motoron controllers are also compatible with Arduino or Python/MicroPython and come with a comprehensive user’s guide.

Please note that the Motoron controllers are not recommended for use with a nominal 5V logic voltage range. The Motoron controllers also come with a reverse-voltage protection feature on the motor power supply, which protects down to −20 V.
