The Premium Edition includes all of the Standard edition features, plus a headset and a Bluetooth module to demonstrate the convenience to pair it with a smartphone via NFC.
The M24SR64 device is a dynamic NFC/RFID tag IC with a dual interface. It embeds a 64 Kbits EEPROM memory. It can be operated from an I2C interface or by a 13.56 MHz RFID reader or an NFC phone.
The I2C interface uses a two-wire serial interface, consisting of a bidirectional data line and a clock line. It behaves as a slave with respect to the I2C protocol.
The RF protocol is compatible with ISO/IEC 14443 Type A and NFC Forum Type 4 Tag.
The board is powered through the USB bus. It also includes a microcontroller STM32F103 to drive the EEPROM via I2C and the LCD screen via SPI bus.
Features:
－ M24SR64-Y Dynamic NFC/RFID tag
－ 31 mm x 30 mm 13.56 MHz double layer inductive antenna etched on the PCB (ANT14)
－ STM32F103RGT6 64LQFP 32-bit microcontroller, with 1Mbytes of Flash memory
－ LCD Color Screen (320*200 pixels)
－ Different color LEDs
－ USB microB connector for board powering
－ JTAG connector for microcontroller firmware upgrade and debug
－ Joystick for menu selection
－ M24SR-DISCO-PREM specific features:
－ Bluetooth module with audio outputs connected to Jack 3.5
－ Headset
