ECM3532 AI Sensor Board

ECM3532 AI Sensor Board

Ultra Low Power Sensor Board for Artificial Intelligence at the Edge.

The ECM3532 AI Sensor board is an ultra-low power AI platform with sensors that can run many algorithms: sound classification, keyword spotting, activity classification, context awareness, defect detection and others.

It showcases the capabilities of the ECM3532 Neural Sensor Processor built with Eta Compute’s patented self-timed continuous voltage and frequency scaling technology (CVFS) producing the lowest energy for inference for machine learning algorithms.
