Product Note

1. Pay attention to wiring according to the diagram and do not make mistakes.

2. The card frequency used must be 13.56MHz

3. The power supply voltage should not exceed the maximum voltage that the module can withstand, otherwise the module will be damaged.

4. This document only represents the product knowledge and parameters at the time of editing, and any changes in the future will not be notified separately.

5. During use, there should be no metallic material between the module sensing area and the card, otherwise the card cannot be read.

Product Overview

The module adopts MFRC522 chip to design the card reading circuit, which is easy to use and suitable for users of advanced applications such as device development and card reader development, as well as users who need to design/produce RF card terminals. This module is suitable for installing various card reader molds. The module adopts a voltage of DC3.3V and can directly communicate with users' 51, ARDUINO, STM32 and other microcontrollers through SPI interface. The module works stably and reliably, with a long card reading distance.
