(SPIDER Automation) STMicroelectronics X-NUCLEO-NFC02A1 Dynamic NFC/RFID Tag Expansion Board | M24LR04E-R Shield for STM32 Nucleo

STMicroelectronics X-NUCLEO-NFC02A1 Dynamic NFC/RFID Tag Expansion Board | M24LR04E-R Shield | For STM32 Nucleo IoT Connectivity

Description

SPIDER Automation STMicroelectronics X-NUCLEO-NFC02A1 Dynamic NFC/RFID Tag Expansion Board provides developers with a versatile platform for implementing contactless communication, parameter configuration, and data exchange in embedded designs. Powered by the M24LR04E-R NFC Type V / RFID tag IC, the board bridges the gap between traditional wired microcontrollers and wireless mobile devices through a dual-interface 4 Kbit EEPROM.

The EEPROM is structured for seamless flexibility—organized as 512 x 8-bit over the I2C bus and 128 x 32-bit via the RF interface. Equipped with a custom 30 mm x 30 mm double-layer inductive antenna etched directly onto the PCB, the X-NUCLEO-NFC02A1 can draw operating power either from standard Arduino headers or by harvesting energy straight from an incoming 13.56 MHz electromagnetic field. Fully compatible with STM32 Nucleo boards, it enables rapid prototyping for touch-free device provisioning and IoT data transfer.

Key Features

• M24LR04E-R Secure Tag IC: Advanced dynamic NFC/RFID chip featuring a dual-interface architecture (I2C and RF).
• 4 Kbit EEPROM Memory: Provides ample non-volatile storage with native NDEF (NFC Data Exchange Format) support.
• Onboard Etched Antenna: Integrates a tuned 30 mm x 30 mm double-layer 13.56 MHz inductive loop antenna for optimal RF pickup.
• RF Energy Harvesting: Capable of operating self-powered or harvesting current directly from external NFC reader magnetic fields.
• Dual-Mode Organization: Configured as 512 x 8-bit in I2C mode and 128 x 32-bit in contactless RF mode.
• Standardized Prototyping Layout: Outfitted with Arduino UNO R3 compatible connectors for instant stacking onto host development boards.
• Seamless MCU Interfacing: Communicates smoothly with host microcontrollers over a standard I2C serial bus.
• Compact Shield Form Factor: Engineered for quick integration into existing STM32 Nucleo development stacks.

Benefits

• Contactless Configuration: Allows smartphones or NFC readers to update device settings or read logs even when the host system is powered down.
• Simplified System Integration: Eliminates complex antenna matching design, providing a ready-to-use RF interface right out of the box.
• Flexible Power Architecture: RF energy harvesting capabilities enable batteryless maintenance or backup communication modes.
• Ecosystem Compatibility: Native plug-and-play support with STM32 Nucleo boards and standard development libraries speeds up time-to-market.

Applications

• IoT Device Provisioning: Wireless pairing, network credential input, and initial configuration of smart home appliances via smartphone.
• Industrial Data Logging: Contactless retrieval of diagnostic records, error codes, and maintenance histories from sealed electronic enclosures.
• Consumer Electronics & Toys: Interactive parameter tagging, accessory authentication, and firmware feature unlocking.
• Embedded R&D Laboratories: Educational and commercial prototyping of NFC Type V communication protocols and secure data exchange.
