100% Brand New and High Quality
The dedicated module RDM630 series of non-contact RF ID card, preclude the use of advanced RF receiver circuits and embedded microcontroller design
Combined with efficient decoding algorithms, to complete the EM4100 compatible ID card data reception
This module is convenient to use, the power supply serial connection after for motherboard, when RFID card to enter the card read range, module will be through the UART the card number directly send for
Receiver sensitivity, high operating current, high stability
Suitable for access control, time and attendance, charges, anti-theft, Patrol and other radio frequency identification applications
Frequency: 125KHz
Interface: TTL RS232
Voltage:for DC 5V(±5%)
Current:
