The NFC module combines reading, writing, and card emulation with support for multiple contactless communication standards, simplifying embedded system development.
A new NFC development module has been designed to provide a unified platform for both read and write operation and card emulation under different contactless communication protocols. The NFC development module is based on the RP2040 microcontroller chip and aimed at embedded software developers who require versatility in their NFC functions without the need of specialized NFC controllers.
It is capable of supporting such protocols as ISO14443A, ISO14443B, ISO15693, and FeliCa, allowing it to communicate with a wide range of NFC tags and cards. In contrast to most of the existing NFC modules that can be used only under certain communication protocols or have only certain card emulation features, the new module combines these features into a single hardware platform.
Built on the RP2040 microcontroller, the module uses the RP2040 software development kit (SDK) and provides a standard Grove interface, along with UART, SPI, and USB communication options.
As per the developers, the device eliminates the requirement of a separate NFC controller and can therefore serve as an economical platform to prototype and develop NFC applications. The module also enables quick integration within embedded systems and at the same time supports compatibility with existing NFC communication protocols.
In order to ensure development, the module will include a dedicated software library for low-level NFC hardware operations which would allow programmers to customize NFC functionalities, protocol-specific features, and develop application-specific solutions.
The module is meant to be used for applications like access control, asset tracking, contactless identification, smart devices, industrial automation, and embedded Internet of Things applications.
