TL;DR
Mehrdad Majzoobi has developed an open-hardware near-field communication (NFC) add-on for Raspberry Pi that can function even when the board is powered off. This add-on, part of his Ubo Pod project, utilizes the NXP NT3H2211W0FT1 NFC chip, which offers both active and passive operation modes. In passive mode, it can harvest energy from a reader to communicate, making it useful for applications like tap-based payments without needing the Raspberry Pi to be on.
Why This Was Curated
The article presents a practical hardware project that software developers can engage with, specifically focusing on an NFC add-on for Raspberry Pi. It is accessible and provides actionable insights for developers looking to integrate hardware with software, although it leans slightly towards being informational rather than a step-by-step tutorial.
