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 Control-
lers (DSCs) and Microcontrollers (MCUs). The dsPICDEM MCLV-2 Development 
Board is essentially a backwardly-compatible upgraded version of the dsPICDEM 
MCLV Development Board.

The dsPICDEM MCLV-2 Development Board supports the dsPIC33F, PIC24F, 
dsPIC33E, and PIC24E motor control device families. It offers a mounting option to 
connect a generic 100-pin Plug-In Module (PIM). The board also has a three-phase 
inverter bridge circuit. The circuit drives a BLDC or PMSM motor using different control 
techniques without requiring any additional hardware. Topics covered include:

•

•

 shows a simplified block diagram of the dsPICDEM MCLV-2 Development 

Board. The board includes various circuitry to perform the following functions:

• Drive a three-phase inverter that powers the motor phase windings

• Measure feedback signals (e.g., voltage and phase currents) and provide a 

suitable fault signal

• Interface with Hall sensor or quadrature encoder for sensor-based commutation

• Communicate with a host computer or an external device via CAN, LIN, USB, or 

RS-232 interface

The development board supports motors with terminal voltage up to 48V and current 
up to 15A. Refer to
