Motoron M3H256 Triple Motor Controller for Raspberry Pi (Connectors Soldered)

The Motoron M3H256 Triple Motor Controller is a great solution for controlling DC motors with a Raspberry Pi (Model B+ or newer) via an I²C interface. Each module can handle up to three motors independently. You can stack multiple Motoron boards on one Raspberry Pi for projects requiring more motor control. It operates between 4.5 V and 48 V and can provide continuous output currents of up to 2 A per motor. This version comes with soldered stackable headers and terminal blocks, along with a set of two M2.5 standoffs, screws, and nuts for proper GPIO connector height. It doesn't need PWM outputs on the Raspberry Pi. Instead, it uses I²C, so only two GPIO pins are needed regardless of the number of Motorons connected. Key features include three motor control channels, a wide operating voltage range, high current capacity, reverse-voltage protection, and many configurable parameters. There's also a Python library for easy setup and a comprehensive user’s guide.

Using the Motoron M3H256 is straightforward. First, make sure your Raspberry Pi is Model B+ or newer. Stack the Motoron board on top of the Raspberry Pi and secure it using the provided standoffs, screws, and nuts. Connect your DC motors to the terminal blocks. The Raspberry Pi communicates with the Motoron via the I²C interface, so you'll only need to use two GPIO pins. Before powering on, double - check your connections and ensure the power supply voltage is within the 4.5 V to 48 V range. When programming, you can use the Motoron Python library to quickly get started. This library simplifies the process of controlling the motors. Be careful not to exceed the maximum output current per motor, which is 2.0 A continuous and 6.4 A peak for less than 1 second. If the Raspberry Pi stops communicating, the command timeout feature will stop the motors. For maintenance, keep the board clean and free from dust. If you're using the optional pins to power the Raspberry Pi from the motor power supply, use an external regulator (not included) to ensure stable power.
