M5StickV K210 AI Camera (Without Wifi)

Note: M5StickV does not support for microphone function, which will be added on upcoming Wifi version M5StickV+.

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. We co-oped with Sipeed providing the MicroPython environment makes programming onM5stick-V easier. 

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.
