Features

Ready-to-use printed circuit board including 10 divisible antenna boards. Each of those antenna board can be connected to an MCU thanks to the I 2C interface. The MATRIX-M24SR antenna boards are based on the M24SR64-Y device which is compatible with NFC phones. As such, any NFC phone can communicate with those antenna boards.

  • Various antenna designs – 45 mm x 75 mm 13.56 MHz inductive antenna etched on the PCB (ANT1) – 20 mm x 40 mm 13.56 MHz inductive antenna etched on the PCB (ANT2) – 14 mm x 13.5 mm 13.56 MHz double layer inductive antenna etched on the PCB (ANT7) – 45 mm x 65 mm 13.56 MHz inductive antenna etched on the PCB with a DSILC6- 4P6 external ESD protection (ANT10) – 4.7 µH SMD-inductor based antenna (ANT11) – 2 spare circuits for customer antenna development (ANT12) – Metal Tag 13 .56 MHz inductive antenna etched on the PCB (ANT9) – 20 mm round 13.56 MHz double layer inductive antenna etched on the PCB (ANT13) – 31 mm x 30 mm 13.56 MHz double layer inductive antenna etched on the PCB (ANT14)
  • M24SR64-Y Dynamic NFC/RFID tag IC
