The Motoron M2h18v18 Dual High-Power Motor Controller for Raspberry Pi (Connectors Soldered) is a sophisticated device designed to manage DC motors via a Raspberry Pi (Model B+ or newer) through an I²C interface. It is capable of supporting motor supply voltages ranging from 6.5 V to 30 V and delivering continuous output currents of up to 18 A for each motor. This particular model comes with aluminum standoffs and features soldered stackable headers and terminal blocks.

The design of the M2H controllers allows them to be stacked on top of a Raspberry Pi, akin to a HAT (Hardware Attached on Top). This unique design enables the stacking of multiple controllers on top of each other, thereby facilitating the independent control of numerous motors. The Raspberry Pi communicates with the Motoron via I²C, requiring only two GPIO pins, irrespective of the number of Motorons connected.

The M2H18v18 controller is capable of supporting motor supply voltages from 6.5 V to 30 V and delivering continuous output currents of up to 18 A per motor. This controller can be identified from other M2H controllers by its smaller discrete MOSFETs and the number 150 on the tall silver electrolytic capacitors.

The 5mm blue terminal blocks are rated for up to 16 A, hence for higher-current applications, it is advisable to opt for an unsoldered version and solder thick wires directly to the board.

The controller is equipped with two motor control channels for independent control of up to two bidirectional brushed DC motors, reverse-voltage protection on the motor power supply, and a logic voltage range of 3.0 V to 5 V. It features a control interface: I²C clock speed of up to 400 kHz, configurable motion parameters, current sensing, configurable hardware current limiting, a command timeout feature, configurable automatic error response, motor power supply (VIN) voltage measurement, two status LEDs, and motor direction indicator LEDs. It is also accompanied by a Motoron Python library for easy use with Python or MicroPython and a comprehensive user’s guide.

Important Note: The M2H18v18 controller's absolute maximum voltage is not intended for use with 24 V batteries. For higher-current applications, it is recommended to use an unsoldered version and solder thick wires directly to the board.
