Description

Unit Camera is a high-cost-performance WiFi camera from M5Stack, featuring the ESP32-WROOM-32E control core and a 2-megapixel image sensor (OV2640). Its minimalist design includes no unnecessary peripherals. The pre-installed software integrates image transmission firmware, offering interfaces for image data acquisition and adjustment of image parameters such as white balance, exposure, gain, and size. Users can directly obtain image data and interact with the camera via UART or WiFi. It supports UIFlow graphical programming, allowing for a zero-development, out-of-the-box user experience. Additionally, the reserved program download interface enables users to easily update or customize the firmware, enhancing functionality and performance. The camera also comes with a mounting clip, making it easy to fix in the desired position. Its compact design and high cost-performance make it suitable for various wireless camera application scenarios.
