1. Based on PN532 chip for 13.56MHz near field communication.
2. The module is equipped with an on-board antenna, no external antenna coil is required, and the module is compatible with SPI, I2C, and UART interfaces for communication.
3. With the NFC library supporting Arduino and Raspberry Pi, it can be easily used for the development of NFC-enabled products.
4. Support SPI, I2C and UART interface selection switching
5. Effective communication distance within 5cm
6. Can be used for 13.56MHz contactless communication.
7. Compatible with ISO14443 Type A and Type B standards
Special Tips:
1. If there is a phenomenon that the programme can be compiled but cannot be uploaded successfully: to rule out the failure of the development board, you can first upload the programme to the development board successfully, then connect the card reader module and press the button.
Then connect the card reader module, press reset, and then continue debugging.
2. The toggle switch settings are different for different communication modes. Remember.
