Description

The RFID Reader Module RC522 is a popular RFID (Radio Frequency Identification) module commonly used for communication between microcontrollers and RFID cards or tags. Here are some specifications of the RC522 module:

1. Operating Frequency: The RC522 module operates at a frequency of 13.56 MHz, which is the standard frequency for many RFID systems.

2. Communication Interface: It uses a SPI (Serial Peripheral Interface) for communication with microcontrollers or other devices. The SPI interface allows for high-speed data transfer.

3. Read/Write Capability: The RC522 module is capable of both reading and writing data to RFID cards or tags. It can read the unique identification (UID) of the card and also write data to the card’s memory, depending on the type of card/tag used.

4. Supported Cards/Tags: The RC522 module supports various types of RFID cards and tags that comply with the ISO/IEC 14443 A/MIFARE standard. This includes MIFARE Classic 1K, MIFARE Classic 4K, MIFARE Ultralight, MIFARE DESFire EV1, and more.

5. Operating Voltage: The module typically operates at a voltage of 3.3V, although some versions may support a wider voltage range. It is important to ensure that the module is powered with the appropriate voltage to avoid damaging it.

6. Antenna: The RC522 module has an integrated antenna that is used for communication with RFID cards or tags. The module’s antenna has a limited range, typically a few centimeters, which means the card/tag needs to be brought close to the module for successful communication.

7. Data Transfer Rate: The RC522 module can achieve data transfer rates of up to 10 Mbps using the SPI interface. This high-speed transfer allows for efficient communication with RFID cards or tags.

8. Additional Features: The RC522 module may also include additional features like built-in anti-collision, which helps in handling multiple cards/tags in close proximity without data collisions.

It’s worth noting that different versions or manufacturers of the RC522 module may have slight variations in specifications or features, so it’s always a good idea to refer to the specific datasheet or documentation provided by the manufacturer for precise information about a particular module.
