PN532 NFC RFID Module - 13.56MHz Reader/Writer servo tester which leads to stringing andMost of RFID modules are hardwired for SPI communication. This module, however, is not. The PN532 is an NFC RFID module clocked at 13. 56MHz. What's special about this is that it has an onboard switch that you can use to easily change between I2C, SPI, and TTL Serial. It also has an integrated logic level shifter so you can use either 3. 3V or 5V. Note that this module gets warm in normal operation. Specifications: Supports I2C, SPI, and HSU (High
