Unit CAM

SKU:U109

UIFlow Camera-Tool

Description

Unit CAM M5 launched a very cost-effective Wi-Fi camera, using ESP32-WROOM-32E control core + 2MegaPixel image sensor (OV2640) solution on the hardware, using the most simplified design, no extra peripherals. The factory software integrates image transmission firmware, provides image data acquisition, image parameter (white balance, exposure, gain, size and other attributes) adjustment interface, users can directly acquire image data through UART or Wi-Fi, and interact with the camera. Support UIFlow graphical programming call, realize zero development, out-of-the-box user experience. The compact design and cost performance are suitable for various wireless camera application scenarios.
