Features

• Support external antenna
• Maximum effective distance up to 150mm
• Less than 100ms decoding time
• UART TTL interface
• Support EM4100 compatible read only or read/write tags
• Built-in external bi-color LED and buzzer driver

APPLICATION

• The Seed Studio 125KHz RFID reader module is designed for reading the codes from 125KHz RFID chips/cards and is compatible with read-only tags and read/write tags.
• It could be used in office/home security, personal identification, access control, anti-forgery, interactive toy and production control systems etc.
• The RFID module will notify whenever a 125khz tag approaches, the tag serial number will be sent via the TX pin.
• This is an easy and cost effective way to RFID enabled your MCU (micro controller) project. You can also connect directly to a PC via the UartSB.
