Note:

Kindly take note that the Grove Vision AI V2's Part List does not include a camera. In order to make use of all the features and capabilities of the Grove Vision AI V2, you may need to acquire a CSI camera separately. We recommend using the OV5647-62 FOV Camera Module for Raspberry Pi. Alternatively, you may opt to purchase it as a bundle on the product page.

What are the cores?

The Grove - Vision AI V2 is a highly efficient MCU-based smart vision module driven by the Himax WiseEye2 HX6538 processor, featuring a dual-core Arm Cortex-M55 and integrated Arm Ethos-U55 neural network component. It integrates Arm Helium technology, which is finely optimized for vector data processing, enables a significant uplift in DSP and ML capabilities without compromising on power consumption, which is ideal for battery-powered applications.

How's the performance of Grove Vision AI V2?

To have a quick evaluation of this board's performance, we compared it to Seed's other MCU-based vision AI boards - Grove Vision AI Module, XIAO ESP32S3 Sense in four areas:

Power consumption: This metric indicates whether the board can be used in battery-powered products.
Inference time: This metric indicates the processing speed of the MCU and how much latency is involved.
Frame rate: This metric evaluates whether the product can capture instant changes, patterns, and movements.
Ease of use: We assessed whether this product is user-friendly for vision AI novices and can quickly run mainstream models on the market.
