+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, MEMS Microphone, IPS screen, 6-axis IMU, 200mAh Li-po battery, and more. +

+More than the visioning, M5stick-V also features the embedded APU - Audio Processor. With its hardware beam-forming support and dual 512-point FFT units, the M5stick-V is also capable of a series of machine hearing works like voice wake-up to speech recognition. +

Smaller than the PROTO unit, the size is exactly the same as the regular M5unit. You can have the total freedom to make your own project as you want it, with prototyping boards that allow laying out the customized circuit to interact with the M5 core CONNEXT Port A, B or C. +

+For different CONNEXT ports, you will be able to interact with different pins that ported out from ESP32. +
