An enabler for device interaction, the M24SR discovery kit contains everything engineers need to start adding NFC connectivity to any kind of electrical device, from fitness watches and loudspeakers to washing machines and water meters.
The M24SR dynamic tags combine industry-standard serial-bus (I2C) and contactless RF (NFC Forum Tag Type 4) interfaces. The devices support the NFC data exchange format (NDEF) and 128-bit password protection. They come in EEPROM memory densities from 2 Kbit to 64 Kbit and three package types: SO8, TSSOP8, and UFDFPN8.
The package illustrates NFC use cases such as “tap and pair,” URL connection, send an SMS or an email, and business-card download. It includes a Dynamic NFC/RFID tag (M24SR64-Y), an STM32F1 microcontroller, a 13.56 MHz antenna, an LCD colour screen, a USB connector, a JTAG connector, and a joystick for menu selection. The Premium version adds a Bluetooth module with audio outputs and a headset to demonstrate convenient Bluetooth pairing of a smartphone and an audio device with the M24SR.
