Stellaris® Brushed DC 24 V Motor Control Module with CAN - MDL-BDC24

Not Recommended For New Designs

The MDL-BDC24 is powered by the ARM® Cortex™-M3-based LM3S2616 microcontroller that provides efficient and deterministic performance while integrating CAN, UART, and advanced motion control capabilities. TheMDL-BDC24 design also incorporates several high-quality analog components from Texas Instruments, including the SN65HVD1050 CAN Transceiver, MAX3221 RS232 Line Driver/Receiver, TPS54040 Swift DC/DC Converter, TPS73633 Voltage Regulator, and INA193 Current Shunt Monitor. The MDL-BDC24 is positioned into a wide variety of consumer and industrial applications, including factory automation devices and systems, mobile robots, household appliances, pumping and ventilation systems, and electric wheelchairs and mobility devices.

Module Contents:

The MDL-BDC24 ships with the motor control module encased in plastic. For a complete, open-tooled reference design kit, including motor, cables, and CD containing design files, quickstart, and firmware development package, please see the Stellaris RDK-BDC24. 


The MDL-BDC24 ships as a ready-to-run, yet customizable, module with the following features:

  • Quiet control of brushed DC motors
    • 15 kHz H-bridge frequency
  • Three options for open-loop voltage control
    • Industry-standard R-C servo type (PWM) interface
    • Controller Area Network (CAN) interface
    • RS232 serial interface
  • Two options for closed-loop, speed, position, or current control
    • Controller Area Network (CAN) interface
    • RS232 serial interface
  • CAN communication
    • Full configurability of module options
    • Real-time monitoring of current, voltage, speed, and other parameters
    • Load firmware over RS232/CAN
  • RS232 serial communication
    • Bridges an RS232-enabled device to the CAN
    • Directly interfaces to a PC serial port or National Instruments cRIO
  • Limit switch inputs for forward and reverse directions
  • Firmware features
    • Full configurability of closed-loop module parameters
    • Real-time monitoring of sensor data including motor current, encoder position or speed, and limit switch state
