RC522 RFID Reader IC Card Serial Port RFID Proximity Card Reader Low Power Consumption RF RFID Card Reader Writer
Product Description
The M6 module is a 13.56MHZ high-frequency read-write module. The module comes with CPU control without secondary programming. It can be seamlessly connected to any system without loading any drivers for serial port transceiver. The integrated onboard RF antenna has more stable performance and is very It is suitable for charging piles, self-service sales, and advertising integrated machines.
Features
◆ The module is small in size, easy to install, versatile and easy to develop.
◆ The built-in CPU control does not require the user to edit the program twice, and the IC card can be easily operated only through the serial port protocol.
◆ Complete serial port control, can be seamlessly connected with any system, no need to install additional drivers, only need to connect the four lines of VCC, TX, RX, GND to communicate.
◆ The standard configuration uses 3.3V DC voltage power supply, which can meet the output voltage of most of the serial ports of the development board.
◆ Humanized design, can control the buzzer as a reminder action, onboard power LED light, easy to check the power status.
◆ Complete functions, clear development protocol, support IC card read and write operations, sector encryption, CPU can store 50 characters as flash backup data.
◆ Support mode switching, read-only or read-write mode settings, three output formats can be switched in read-only mode.

Interface parameter description
◆Power input interface The 3.3V DC power supply is used to supply power, and only the computer or development board is allowed to supply power to the board subsystem. The 3.3V DC power supply needs to support a minimum of 100mA current when no peripheral load is connected.
The module has a small size and is connected to a 3.3V input voltage. If you need to use 5V or 9V, please use a step-down chip or customized functions.
◆ Serial communication socket interface You only need 4 wires (VCC, TXD, RXD, GND) to connect to the
corresponding motherboard to complete the serial communication. Pay attention to the output voltage of the motherboard's serial port, select the corresponding matching level signal, and pay special attention to whether the motherboard is a 232 serial port or a TTL serial port.
corresponding motherboard to complete the serial communication. Pay attention to the output voltage of the motherboard's serial port, select the corresponding matching level signal, and pay special attention to whether the motherboard is a 232 serial port or a TTL serial port.
Precautions:
1. The serial port does not communicate, check whether the level does not match, and TTL is connected to 232.
2. Whether the TX and RX connections are correct.
