TENSAI® AI Sensor Board

Getting Started

Users can best experience the versatility of the ECM3532 AI Sensor board in minutes by using Edge Impulse’s TinyML development pipeline and the 6 pin UART port.

See here for a tutorial how to use the board with Edge Impulse: https://docs.edgeimpulse.com/docs/eta-compute-ecm3532-ai-sensor

Accelerates prototyping of AI Sensing 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.
