SainSmart Serial UART 13.56MHZ RFID Reader/Writer Module Kit

This RFID module is designed based on MFRC522. It is a highly integrated reader/writer for contactless communication at 13.56MHz. It supports ISO 14443A/MIFARE mode and MIFARE Classic (e.g. MIFARE Standard) products. Contactless communication using MIFARE higher transfer speeds up to 848kbit/s in both directions.

We embedded an MCU on this module. By sending command via UART interface, you can make it work. Operation is very easy. Most work is done by the embedded MCU. There is also a SPI interface on the board. This is the MFRC's SPI. You can access MFRC directly via this interface.

Specifications:

* Power Supply: 4.5V~5.5V, typically 5V. ( Interface: UART (5V TTL) and SPI (3.3V TTL)
* Size: 40mm x 50mm
* Baud rate could be 2400bps ~ 115200bps

Default setting:

* Baud Rate: 9600bps
* Parity bit: None
