Discovery Kit for CR95HF Reader and M24LR04E Dynamic NFC/RFID Tags with Energy Harvesting

M24LR-DISCOVERY

Overview

M24LR-DISCOVERY is a ready-to-use kit which features the M24LR04E-R Dual Interface EEPROM IC. It addresses a wide range of applications such as industrial or medical equipment and consumer electronics. This kit contains 2 different boards, as shown in the figure on cover page.

The M24LR board is battery-less and is powered by RFID readers or NFC-enabled phones supporting ISO/IEC 15693.
The RF transceiver board is an RFID reader demonstration board and is composed, among other parts, of a CR95HF (13.56 MHz multi-protocol contactless transceiver IC with SPI and UART serial access). This board has to be plugged in to a PC and comes with a demonstration software.
The M24LR board also works with Android NFC phones supporting ISO/IEC 15693. An application called NfcV-Reader is available on Google Play. Performance may vary depending on NFC phone's RF management.
