Description
UNIT-V M12 is an AI camera unit with M12 lens specifications and K210 processor, which integrates dual-core 64-bit RISC-V CPU and neural network processor edge computing system-on-chip, it equippes with M12 optical lens OV7740 wide-angle camera module (can replace other M12 lenses), the body is equipped with two programmable buttons and TF card expansion slot. Its bottom provides an HY2.0-4P interface and a TYPE-C interface for data connection to the controller. The UNIT-V M12 AI camera is very small, it is suitable for embedding in various devices, with machine vision processing capabilities, supporting a variety of image recognition capabilities (such as real-time acquisition of the size and coordinates of the detected target Real-time acquisition of the type of detected target), and it can perform convolutional neural network calculations, which is a low-threshold machine vision embedded solution.

FAQ
Question: What should I do if the computer does not detect Device?
- UnitV may not work without a drive in some systems, and users can fix this problem by manually installing FTDI drivers ( https://ftdichip.com/drivers/vcp-drivers/ ). Taking the Win10 environment as an example, download the driver file that matches the operating system, extract it, and install it through Device Manager. (Note: In some system environments, you need to install twice before the driver takes effect, the unrecognized device name is usually M5Stack or USB Serial, Windows recommends using the driver file to install directly in Device Manager (custom update), the executable file installation method may not work normally).
