UART 125Khz EM4100 RFID Card RFID Reader Module For Arduino Fingerprint ID Card Module Parking Lot Access Control Card Reader

Features:

Product introduction: The 25KHZ EMID card reader module features small operating current and high stability. It can be used in attendance systems, access control systems, parking management systems, food sales systems, electronic security systems, community management, elevator control, lockers, toys, etc. The RFID reader module can read 125K EM4100 series (or compatible) RFID cards. The module is very convenient to use, connected to the matching card reader antenna (coil) serial port to connect the single-chip microcomputer, turn on the power. When an RFID card enters the card reading range, the module automatically sends the card number through the serial port (UART), after receiving the MCU Can control the relay to achieve simple access control. Module size and pinout instructions: Model:70714 1.GND: power ground 2.VCC: +5V 3.TXD: card number serial output 4.XH: Connect LED 5.LS: Connect the buzzer 6.L1: Receive card antenna 7.L2: Receive card antenna Parameter: Power: 3-5V, <25MA Working frequency: 125KHZ±1KHZ Card reading distance: <7CM distance is related to card and antenna size Output mode: serial port TTL-232 level Card reading method: swipe the card once and output the card number once Card reading temperature: <100MS Working temperature: -10~75 degree Coil inductance: 345uH Application: Card reader module can be applied to attendance system, access control system, parking management system, food sales system, electronic anti-theft system, community management, elevator control, lockers, toys, etc.
