It is characterised\nby high reception sensitivity, low operating current and high stability. The\nsupport module commonly used by users for reading radio frequency\nidentification cards can read EM4100 series 125K radio frequency\nidentification cards. This module is easy to use. After turning on, connect\nthe serial port to your motherboard. When a radio frequency identification\ncard enters the card reading area, the module sends the card number directly\nto the motherboard via UART. Then use the relay module to connect to the\nmotherboard to achieve easy access control. APPLICATION Suitable for various\napplications of radio frequency identification such as access control,\nattendance, charging, anti-theft, patrol service, etc. Module parameters:\nFrequency: 125 kHz. Baud rate: 9600 (TTL current level format). Interface: TTL\nElectricity LevelFormat Power supply: DC 5V (± 5%) Current: \u0026lt;50 mA.
