GZ01 Dul frequency 5V TTL  reader module 

GZ01 reader module, integrated high performance card reading radio frequency circuit and antenna; and it also supports ID and IC card, and UART interface to output data.

Small size allows it to be widely applied to more devices, such as fingerprint machine, attendance machine, entrance guard.

Features:

1>. Voltage: DC 5V

2>. Current: 40mA

3>. Support 125KHz and 13.56MHz (ISO14443A) card

4>. Interface: UART

5>. Size: 47*26*6mm (main board ) ,Size for antenna board :32*26*1mm

6>. Operating Temperature: -20~70 Celsius

7>. EM4100 Card Reading Distance: >5cm

8>. MF S50 S70, Desfire, FM1208 Card Reading Distance >3cm

9>.UART Interface Output

For example: the data received by serial port tool is 02 0A 02 2E 00 B6 D7 B5 F2 03, then

   1).The first byte 0x02 means data start.

   2).The second byte 0x0A means the whole data length is 10 bytes, which includes data start and data end.

   3).The third byte 0x02 means the card type is EM4100

   4). The fourth to eighth byte (0x2E 0x00 0xB6 0xD7 0xB5) means the read card number, and the fourth byte 0x2E is hidden card number

   5). The ninth byte 0xF2 means BCC check of second byte to eighth byte.

   6). The tenth byte 0x03 means data end.

Notice:

1). Keep away from interference source, and strong interference signal may affect card reading

2). Select linearity power can improve the card reading distance and effect; switch power may attenuate the distance but will not influence normal operation

3). The module can operate normally in the range of 3-5V, please do not use higher voltage

4). This module has high frequency signal, so it may cause some interference to the analog circuit. Uses should place the module a little far away from the buzzer;

if the distance is too close, the sound of the buzzer will be low.

Applications:

1>.Attendance Fingerprint Read Write Module

2>.Entrance Guard Intercom Read Write Module

3>.Replicator

4>.Attendance fingerprint card reader module

5>.Entrance guard intercom card reader module
