The dsPICDEM MCLV-2 Development Board provides a cost-effective method of evaluating and developing sensored or sensorless Brushless DC (BLDC) and Permanent Magnet Synchronous motor control applications. The board supports Microchips 28-pin SOIC and a variety of Plug-In Modules with dsPIC33F/E Digital Signal Controllers. With the MCLV-2 either the internal, on chip OpAmps or the external OpAmps on the MCLV-2 board can be used. Microchip provides PIMs for using either the internal or external OpAmps. The MCLV-2 is fully backwards compatible with the original MCLV and all MC PIMs. The board is capable of controlling motors rated up to 48V and 15Amps. This board is designed to work with the 24V BLDC Motor (AC300020) and the 24V motor power supply (AC002013) to create a complete 24V BLDC development kit. This board also supports multiple communications channels such as USB, CAN, LIN and RS-232.

The dsPICDEMTM MCLV-2 Development Board is targeted to control a Brushless DC (BLDC) motor or Permanent Magnet Synchronous Motor (PMSM) in sensor or sensorless operation. This flexible and cost-effective board can be configured in different ways for use with Microchip’s specialized motor control digital signal controllers. The dsPICDEMTM MCLV-2 Development Board supports the dsPIC33E or dsPIC33F motor control device family. It offers a mounting option to connect either a 28-pin SOIC device or a generic 100-pin Plug-In Module (PIM).
