NFC is a popular technology in recent years. We often hear this term when smartphone companies introduce their latest high-end phones. Almost all high-end phones in the market support NFC. Near Field Communication (NFC) is a set of standards for smartphones and similar devices to establish radio communication with each other by touching them together or bringing them into close proximity, usually no more than a few centimeters. For electronics enthusiasts, there is interest in using NFC technology to create custom projects. This NFC RFID module is built around the NXP PN532 chip, which is widely used in NFC applications. The manufacturer provides extensive technical documentation to support developers, and this module was developed based on official reference materials. A software library has also been created to simplify integration and usage. Most of the IO pins from the NXP PN532 are broken out on this module, allowing users to easily connect and experiment. When used with compatible sensor shields, the module supports plug-and-play functionality. For users wishing to utilize alternative interfaces such as UART or SPI, the necessary pins are accessible and easy to connect.
