Unit CAM
SKU:U109
Description
Unit CAM is a cost-effective WiFi camera launched by M5. It uses the ESP32-WROOM-32E control core and a 2MP image sensor (OV2640) in its hardware design, adopting a minimalist approach with no unnecessary peripherals. The factory software integrates image transmission firmware, providing interfaces for image data acquisition and image parameter adjustments (such as white balance, exposure, gain, size, etc.). Users can directly obtain image data and interact with the camera via UART or WiFi. It supports UIFlow graphical programming, enabling a zero-development, out-of-the-box user experience. The compact design and cost-effectiveness make it suitable for various wireless camera application scenarios.
