The OP8666 DSP controller board is based on the popular TI C2000 series of microcontrollers that support direct programming from MATLAB Simulink, PSIM as well as embedded C making it capable of handling advanced control algorithms. This versatility is especially powerful for power electronics applications, where the OP8666 can be used for Rapid Control Prototyping (RCP) and conventional embedded development. It’s a perfect tool for validation of power converters control methods. Keeping that in mind, the OP8666 was designed to benefit fully from the RCP functionality while providing maximum integration and communication options.
The OP8666 DSP controller board is designed especially for academic institutions and R&D facilities for them to have an enclosed, compact, plug-and-play controller, ready to use out of the box. We think that students, professors, and researchers should spend their time developing control system solutions, not assembling and wiring their own controllers. At this price point, the OP8666 is the way to go.
Great for RCP and for conventional embedded development
Save time and effort by accessing a vast library of open-source models and teaching resources.

16 Digital Outputs
16 Analog Inputs
The OP8666 interfaces directly to OPAL-RT real-time simulators through the DB37 connectors on the rear panel. This enables a low cost RCP controller HIL solution, which can reduce the development time and increase flexibility without investing on the hardware prior to finalizing the control system.

The DSP controller board is built around a TI Dual-Core C2000, 200 MHz Controller. Analog in signals are converted to digital signals through the internal Analog to Digital Converter (ADC). All ACD channels has a pre-buffer stage. Each ADC channel has a pre-buffer stage, which sets high impedance to the input, while increasing the input voltage range to ±10V which is commonly used by most HIL simulators and high accuracy sensors. The OP8666 uses an isolated CAN Transceiver IC ISO1042 from Texas Instruments as a bridge to connect the microcontroller CAN-A to a CAN bus. The OP8666 also incorporates fiber-optic communication that can be used in a daisy chain, which has its own applications such as distributed control systems but without master-slave controllers.
