Low Voltage Motor Control Development Bundle (Signal Board & Drive Board) (DV330100)
The Low Voltage Motor Control Development Bundle provides a cost-effective method of evaluating and developing dual/single motor control power stage targeted to drive two Brushless DC (BLDC) motors or Permanent Magnet Synchronous Motors (PMSM) concurrently. The bundle comes with adsPIC DSC Signal board, Motor Control 10-24V Driver Board and dsPIC33EP512GM710 Dual Motor Control PIM.
The dsPIC (DSC) Signal Board supports both 3.3V and 5V operated devices for various applications andfrequently used human interface features along with the communication ports. The Signal Board has two major connectors, a 120-pin connector and a 60-pin connector to enable connection to the plug-in boards.
The Motor Control 10V–24V Driver Board (Dual/Single) along with the compatible dsPIC DSC Signal Board provides a software development platform to build and evaluate embedded motor control application software using Microchip’s high performance motor control Digital Signal Controllers (DSCs) and Microcontrollers (MCUs).
120-pin power board interface connector for power application board
60-pin expansion connector for adds-on boards
