dsPICDEM™ MCLV-2 Development Board (Low Voltage)

Part Number: DM330021-2

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 Microchip’s 100-pin Plug-In-Modules with dsPIC33E, dsPIC33F and PIC32MK Digital Signal Controllers. The board supports the use of the internal, on chip OpAmps found on certain dsPIC® devices or the external OpAmps found on the MCLV-2 board. A dsPIC33EP256MC506 Internal OpAmp PIM (MA330031) is included. The board is capable of controlling motors rated up to 48V and 15A, with multiple communication channels such as USB, CAN, LIN and RS-232.

The dsPICDEM™ 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 dsPICDEM™ MCLV-2 Development Board supports the dsPIC33E, dsPIC33F and PIC32MK motor control device families. It offers a mounting option to connect a generic 100-pin Plug-In Module (PIM).

The MCLV-2(DM330021-2) replaces the previous MCLV (DM330021) and is fully backwards compatible with the previous MCLV(DM330021) and all motor control PIMs
