Product Features

The GRC Dev Board is a development kit and reference design that simplifies prototyping and testing of advanced industrial AIoT applications such as Anomaly Detection and n-Class Classification for predictive maintenance.

High-performance speed is achieved due to the use of reservoir computing methods implemented in the GRC AI Module.

The GRC Dev Board allows

• Promptly testing ready-made, pre-configured neural network;
• Checking the viability of ML algorithms in solving your particular tasks;
• Selecting AI functionality which will suit best to your goals;
• Developing SW, debugging and testing for your target device.

The GRC Dev Board provides functionality for simple sensors connection, on-the-fly software development and debugging, i.e.

• Sensors management and control
• Data pre-processing
• Data formatting for their further processing in the GRC AI Module
• Data flow transfer onto the GRC AI Module
• GRC AI Module management and control
• GRC AI Module results output
• Data post-processing
• Results shown on OLED display and/or via LEDs
