3.35V RFID IC Card Reader Wireless Module, UART Interface Builtin Antenna IC Key Reader Module, RDM6300 Compatible RFID Reader Module for DIY Access Control Projects

This RFID IC reader module is a compact wireless radiofrequency identification unit with builtin antenna, fully compatible with RDM6300 output format. It works under 3.3V5V widerange DC power supply, which can be directly powered by most singlechip microcomputers and embedded control boards. It adopts UART TTL serial communication interface, outputs card ID data when detecting nearby IC cards or key fobs, convenient for user secondary programming and development. Thanks to the integrated onboard antenna, users do not need to match extra external antenna, simplifying hardware assembly. It can stably read standard IC cards and keychain tags within the effective sensing distance. No complicated configuration is required for basic cardreading function. Please note this module is only for reading IC card ID information; it cannot write or encrypt card data. Make sure your main controller supports UART TTL level before wiring. Perfect for DIY accesscontrol system making, student electronicdevelopment experiments, intelligent equipment transformation and cardrecognition related embedded projects.
