RFID-UART module, with read/write capability. Includes card and keychain Mifare tags plus 4 dupont cables.

 

 

 

 

 

The RFID-UART module includes 2 RFID tags and 4 dupont cables, and has the following general description:

The RFID-UART module is designed based on 2 surface mount integrated circuits with a high level of integration:  the RC522, which is an RFID reader,  and the STC12C5A16, a processor that facilitates UART connection to the serial port of any microcontroller simply and quickly at TTL levels.

It has a 4-pin connector with TX and RX signals, 5v. and ground. Its main feature is to allow user control of the RFID system, by simple UART commands sent by a microcontroller.

For example, the microcontroller may request the Mifare tag's serial number sending the command '01 'through the serial port.

 

 

 

 

 

Model: RFID-UART read-write data, based on NPX chip MFRC522, and STC12C5A16 processor.
