This is a high-precision integrated finger vein module. The module is equipped with 32-bit ARM -M4F , and the main frequency of work is as high as 144MHz. It supports floating-point algorithm operations and instruction sets. The module adopts a fully enclosed design. There is no other exposed device except the wiring terminal, and the waterproof level reaches IP56. It has three industrial-level three- standards. The exposed part of the structural waterproof level is as high as IP66. The module port supports the standard design of the fingerprint industry, and has self-adaptability, allowing users to apply and develop seamlessly. Applicable to the application of direct-board smart locks, slider smart locks, embedded locks, glass door locks, apartment rental house locks, various small smart cabinets, simple access control and other products. The straight-board intelligent lock-type means of venous module with a thickness of 13.5mm. High-precision setting into a single -board circuit design scheme, there is no plug-in internally, and the design is highly reliable. Module's standby power consumption is less than 2UA, the work power consumption is less than 43.0mA. Refers to the design of the venous module port and the design of the fingerprint industry, and the application development is seamlessly connected. Strong anti-interference ability, support for use below 30000lux. Note:Due to different production batches, there are differences in printing/appearance, which does not affect use.
