Motoron M3H256 Triple Motor Controller for Raspberry Pi (No Connectors or Standoffs)

The Motoron M3H256 Triple Motor Controller is a great solution for controlling DC motors with a Raspberry Pi (Model B+ or newer). It uses an I²C interface, which means you only need two GPIO pins on your Raspberry Pi, no matter how many Motoron controllers you connect. Each module can independently manage up to three bidirectional, brushed DC motors. You can stack multiple Motoron boards on the same Raspberry Pi for projects requiring control of more motors. Operating from 4.5 V to 48 V, it can supply continuous output currents of up to 2 A per motor. This version comes without header pins, terminal blocks, or mounting hardware, perfect for those who want to solder wires directly or use different connectors. The Motoron doesn't need any PWM outputs on the Raspberry Pi. It offers a wide range of features like reverse-voltage protection, configurable motion parameters, and an optional cyclic redundancy checking. There's also a command timeout feature to stop motors if communication with the Raspberry Pi stops. The Motoron Python library makes it easy to get started, and there's a comprehensive user’s guide.

Using the Motoron M3H256 Triple Motor Controller with your Raspberry Pi is straightforward. First, make sure your Raspberry Pi is Model B+ or newer. Since this version doesn't come with connectors or mounting hardware, you'll need to solder wires directly to the board or use your own connectors. Connect the Motoron to the Raspberry Pi using the I²C interface, which only requires two GPIO pins. You can stack multiple Motoron controllers on top of each other to control more motors. When powering the system, ensure the voltage is between 4.5 V and 48 V. The maximum continuous output current per motor is 2 A, and the peak current can reach 6.4 A for less than 1 second. Be careful not to exceed these limits. The Motoron has reverse-voltage protection down to -40 V, but still double - check your connections to avoid any damage. You can configure motion parameters like acceleration, starting speed, and direction change delay according to your project needs. The command timeout feature is there to stop the motors if the Raspberry Pi stops communicating, so don't disable it unless you're sure. To maintain the controller, keep it in a clean and dry environment. If you notice any overheating or abnormal behavior, check the power supply and connections. The Motoron Python library can help you quickly set up and start using the controller. Refer to the comprehensive user’s guide for more detailed instructions and troubleshooting tips.
