M5StickV K210 AI Camera (without wifi)

M5Stack recently launched the new AIOT(AI+IOT) Camera powered by Kendryte K210 -an edge computing system-on-chip(SoC) with dual-core 64bit RISC-V CPU and state-of-art neural network processor.

M5stick-V AI Camera features its integration with machine vision capabilities, featuring the unprocessed acceptability to AI Visioning with high energy efficiency and low cost. They have worked with Sipeed to provide the MicroPython environment making programming on M5stick-V easier for you.

The module comes with the OmniVision OV7740 sensor, using the OmniPixel®3-HS technology, providing a best-in-class low light sensitivity, making it ideal for machine vision. In addition to an OV7740 sensor, M5stick-V features more hardware resources such as a speaker with built-in I2S Class-D DAC, IPS screen, 6-axis IMU, 200mAh Li-po battery, and more.

The M5StickV is great for:

• Face recognition
• Object detection/classification
• Obtaining the size and coordinates of a target in real-time
• Obtaining the type of detected target in real-time
• Shape recognition
• Video/Display
• Game simulator

Please Note:

• This module does not support microphone functions.
