CPT-DD28035 - Dual TMS320F28035 MCU Board


The CPT-DD28035 is a low cost standardized dual MCU controller board designed to provide a fully flexible interface between dual TMS320F28035 MCUs and a user customised DD Series motherboard. The board has been designed to meet different user interface requirements whilst providing a 4 layer MCU core with basic on-board functionality.

The board contains two Texas Instruments TMS320F28035PN MCUs, which have been specifically developed for use in digital motor/motion control applications.
