SMD RED Smart Brushed Motor Driver with Speed, Position and Current Control Modes

• Brushed DC motor driver of Smart Motion Devices (SMD) product family
• Supports 9-12Vdc motors, 2.5A continous, 5Apeak power, bi-directional
• Open-loop or closed-loop (velocity, position, torque) control modes
• Quickly test functionality and auto-tune motors with SMD UI software

ACROME SMD Red Brushed DC Motor Driver is a specifically designed smart motor control and driver board for robotics and mechatronics projects based on ACROME’s SMD product family. This product is connected to a master controller (such as PC, Raspbbery Pi, Arduino…), sends&recieves commands to this master controller in order to control the DC motor and optional SMD Add-On Modules as well. It communicates with the master controller through an optimized RS-485 communication protocol using APIs available in Pyhton, Arduino IDE and Java. Due to the daisychain connection capabilities, up to 255 SMD Motor Drivers can be connected to a single master controller. As the SMD Red DC Motor Driver runs the intensive motor control code onboard, increase in motor count will not add additional CPU load to the master controller.

Other features:

– Onboard auto-tune function

– Optimized daisychain network for multi-motor applications (up to 254 motors)

– Works with PC or popular controllers like Raspberry Pi 3/4/5, Jetson, Arduino (Gateway modules required)

– Simple and well documented Python, Arduino and Java library

– Communicates with an optimized RS-485 protocol, through convenient RJ-11 connectors and cables

– Offloads the CPU of the main controller by handling all motor control tasks onboard

– Input and output connectors available for an easy daisy-chain connection

– Onboard Over-current, over-temperature, short-motor-circuit protection

This product also features a seperate daisy-chain network for optional Add-On Modules. The Add-On modules can be used for different simple or complex input and output tasks such as ultrasound sensing, light measurement, IMU sensing etc. The Add-On module network is connected to the RJ-45 socket carrying the I2C bus and power rails inside (Power over RJ45), with noise/EMI protected CAT5/6 cables, which helps users to place the Add-On Modules (ie. sensors etc.) anywhere in the application/robot, power them and access them from the SMD Red directly. This reduces wire clutter, code complexity thus increase the modularity. Please see Add-On module products’ description to learn more.

Note: This product requires a power source (9-16V), a gateway module and a controller to operate. Consider purchasing SMD RED Starter Kit or Education Kit if you are using SMD products for the first time:
