The world of machine learning keeps getting tinier and tinier — and with their second ECM3532-based board, Eta Compute has shrunken machine vision applications to a diminutive 1.5 square inches! Based on the same silicon as their AI Sensor Board, the new AI Vision Board features an on-board Himax HM0360 (as featured on Himax's own WE-I Plus EVB Endpoint AI Development Board), as well as tight integration with Edge Impulse Studio, enabling rapid development of low-power AI vision solutions.

In addition to the Cortex-M3-based ECM3532 Neural Sensor Processor, the AI Vision Board is equipped with an ambient light sensor, microphone, and accelerometer/gyroscope — as well as an expansion connector for power and UART communication. In case you don't already have one lying around, Eta Compute thoughtfully include a SparkFun FTDI Basic Breakout (3.3V! The AI Vision Board is not 5V tolerant!), since there is no on-board microUSB or other dongle-free programming interface (advanced users can also take advantage of the integrated SWD CoreSight connectors for the ECM3532 and A31R118 BLE). Bluetooth Low Energy facilitates low-power communication with the device, and a microSD card slot provides additional RF options, in addition to storage. And speaking of storage, the board features a whopping 64 Mbit of serial flash, meaning plenty of space for your largest tinyML models, or extensive data logging! A CR2032 coin cell battery holder, red and blue LEDs, and an action button round out the package, giving you everything you need for a wide range of applications, on a single, power-optimized board.

Despite its small size and low power consumption, the AI Vision Board is capable of some mighty tasks. Applications include sound classification and keyword spotting using the built-in microphone, gesture and defect detection using the accelerometer/gyroscope, and a slew of vision-based tasks such as image classification as well as person and object detection and counting.

A look at its key features:

  • ECM3532 Neural Sensor Processor with hybrid multi-core Cortex-M and DSP operating up to 100MHz with continuous voltage and frequency scaling technology (CVFS)
