Description UnitV-M12 is an AI camera unit with an M12 lens specification and a Kendryte K210 processor. It integrates a dual-core 64-bit RISC-V CPU and a neural network processor edge computing system-on-chip, providing strong hardware support for embedded machine vision applications. The included OV7740 wide-angle camera module follows the M12 optical lens specification and supports replacement with other M12 lenses for different shooting scenarios. The compact body includes two programmable buttons, a microSD card expansion slot, a HY2.0-4P interface, and a Type-C interface for data connection with the main controller. UnitV-M12 supports multiple image recognition functions, including real-time acquisition of target size, coordinates, and type information. It can also perform convolutional neural network calculations, making it suitable for low-threshold embedded machine vision solutions.
