Grove Vision AI V2 Features Himax WiseEye2 and Arm Ethos-U55 MicroNPU


SeedStudio has recently introduced the “Grove Vision AI V2” An AI-based camera module based on the HiMax WiseEye2 HX6538 dual-core Cortex-M55 AI microcontroller. The module works with an OV5647 camera module, and can be used for AI computer vision applications.

Previously we have covered Tokay Lite, ADLINK AI camera, UnitV2, and many other AI camera modules, feel free to check those out if interested in the topic.

The HiMax WiseEye2 HX6538 is a high-performance, ultra-low power AI microcontroller, featuring an Arm-based Cortex M55 CPU and Ethos U55 NPU, designed for a wide range of AI applications including industrial automation, smart cities, and IoT devices. This chip is designed in a joint effort by Himax Technologies and Seeed Studio, as a result, it now has a 32-fold increase in inference speed and 50-fold improvement in energy efficiency over its predecessor H6537, making it a leading choice for endpoint AI solutions and innovations in vision AI.
