features:1. MF-ST40 face recognition module is designed based on Boliu BL808 chip. WIFI function, SPI screen interface, USB interface, multi-channel UART interface and circuit are reserved in the module, which greatly improves the integration of the 's entire product.2. MF-ST40 module is equipped with live face recognition algorithm, compatible with the industry's mainstream serial communication protocol, and can directly replace the original face recognition module with MF-ST40 module without modifying the main control board.3. The MF-ST40 module can be combined with WIFI drive screen motherboard to form a very cost-effective [face recognition+'s eye] solution.Specifications:Color: blackMaterial: PCBProcessor: Boliu BL808 (dual core RISC-V AI chip)Recognition distance: 0.35m~0.9mRecognition speed: 1.0 seconds from power on to unlockingRecognition : H50 V70 (0.8m horizontal distance, recognizable height range: 1.3~2m)Identify the environment: the environment without light can also be recognizedNumber of : 128/1024Power consumption: maximum power during single unlocking: 1.2W; Single unlocking power consumption: 0.36mWhAudio: support the connection of one electret microphone (2P 1.25mm terminal); Support the connection of one 3W speaker (2P 1.25mm terminal)Interface:1.
