This product is a high-precision integrated finger vein module, equipped with a 32-bit ARM -M4F core, the operating frequency is up to 144MHz. Supports floating-point algorithm calculation and instruction set. The module adopts a fully enclosed design, with no other exposed components except for a wiring connector, achieving a waterproof rating of IP56. The module interface is compatible with the fingerprint industry standard and features USB port adaptability, more convenience for integration and development. It is suitable for applications such as slim handle smart locks, sliding smart locks, embedded locks, glass door locks, apartment and rental locks, various small smart cabinets, and basic access control systems, etc. Slim handle finger vein module with a mounting thickness of 13.5mm,High-precision integrated design, only reserved one connector for host devices, high design reliability Based on SOC microcontroller system architecture, with high computing efficiency of the finger vein algorithm engine The standby power consumption is less than 2uA, working power consumption is less than 43.0mA, and the power-up response time is less than 20ms, making it one of the products with excellent energy efficiency optimization in the industry Adopts a fully enclosed design, without any exposed components except for a wiring connector, and the waterproof level reaches IP56. Conforms to industrial-grade Triple-Proof standard, and the waterproof level of the exposed part is as high as IP66 The module interface is compatible with the fingerprint industry standard, more convenience for integration and development The module algorithm features adaptability, and supports both fingerprint protocol and private protocol Strong anti-interference capability, supports use in environments below 30000LUX Finger Vein Recognition:Different from the fingerprint module to read the fingerprint image, the finger vein module uses the infrared imaging principle to collect the vein distribution image inside the finger and obtain the characteristic value for live recognition. For users whose fingerprints are unclear or missing, the finger vein module is a good choice.
