Microchip dsPICDEM MCLV-2 Development Board (DM330021-2)

Detailed Description

The board supports Microchip’s 28-pin SOIC and 100-pin Plug-In-Modules with dsPIC33E or dsPIC33F 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 15 Amps, with multiple communication 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).

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
