Elecfreaks Planetx RFID Module Ef05047

The RFID sensor uses radio frequency to read and write recording media (electronic tags or RFID cards) to identify targets and exchange data.
It features an RJ11 4P4C connection (I²C interface), works at 3.3 V, draws around 50 mA, and uses the PN5321A3 core IC.
You can connect it to the I²C port on an expansion board (e.g. Nezha) and program it using MakeCode or similar environments to read and write RFID tags.
