The MCP series from Basicmicro (formerly Ion Motion Control) are a family of rugged, high-performance motor controllers with scripting support and other advanced features. They can supply brushed DC motors with 30 A, 60 A, or 120 A continuous at voltages from 10 V up to 60 V (depending on the model).

Each MCP motor controller has a USB interface that acts as a virtual serial (COM) port, allowing it to be controlled directly from a computer, and it features built-in commands for controlling acceleration, deceleration, distance, speed, voltage and current limits, and more. Several other interface modes are supported by the MCP as well: it can be controlled via TTL serial, RS-232 serial, or CAN bus (using the CANopen protocol) for use with an embedded or industrial system; RC hobby servo pulses for use as an RC-controlled electronic speed control (ESC); or analogue voltages for use with potentiometers or analogue joysticks.

The MCP features an internal user scripting system and user-configurable I/O pins that allows it to be used as a standalone controller, eliminating the need for an additional processor in many situations. It can be operated without feedback for open-loop speed control, or it can be used with a variety of feedback types for closed-loop speed or position control. A wide range of closed-loop sensors are supported, including quadrature encoders, analogue encoders, and potentiometers.

The MCP incorporates several protection features including temperature, current, over-voltage, and under-voltage limits. Several user-definable settings such as a maximum current limit and battery voltage limits are provided for more refined control. The controller uses regenerative braking but can be configured with a voltage clamp circuit to limit the regenerative voltage when used with switching power supplies.

The MCP233 operates from 10 V to 34 V and can deliver a typical continuous output current of 30 A per channel. It has a USB Mini-B connector and a female DA-15 connector (sometimes called DB-15) for control, feedback, and user I/O.

Up to 6 user inputs are available, all of which can be configured as analogue, PWM, or digital inputs. 2 user outputs are available; these are open-drain (they can drive low to sink up to 3 A or be set to high impedance) and are 40 V tolerant.

Key Features

  • Simple bidirectional control of two brushed DC motors
  • 10–34 V or 10–60 V operating supply range, depending on controller model
  • 30 A to 160 A maximum continuous current output, depending on controller model
  • Channel bridging allows control of a single motor with double the current capability
  • Automatic current limiting reduces duty cycle when temperature exceeds 85° C
  • Six communication or control options:
    1. USB serial interface (virtual COM port)
    2. 3.3 V logic-level (TTL) serial interface for direct connection to microcontrollers or other embedded controllers
    3. RS-232 serial interface
    4. CAN bus interface supporting CANopen protocol as master or slave device
    5. Hobby radio control (RC) pulse width interface for direct connection to an RC receiver or RC servo controller
    6. Analogue voltage (0 V to 5 V) interface for direct connection to potentiometers and analogue joysticks
  • Automatic control switching with user-defined priority settings
  • I²C interface accessible by user script
  • Up to 20 user-defined input pins for control, feedback, or scripting, depending on controller model
