Product details

Overview

X-NUCLEO-NFC03A1 from STMicroelectronics is an NFC card reader expansion board based on the CR95HF and ST25R95 analog front-end ICs, designed for plug-in evaluation and development with STM32 Nucleo boards. It supports ISO/IEC 14443 A/B, 15693, 18092, and MIFARE Classic protocols, features a 47 mm × 34 mm four-turn 13.56 MHz PCB antenna, and communicates via SPI or UART with host microcontrollers.

For engineers reviewing the X-NUCLEO-NFC03A1 datasheet, X-NUCLEO-NFC03A1 pinout, X-NUCLEO-NFC03A1 application, or X-NUCLEO-NFC03A1 equivalent, this board delivers FCC-certified, RoHS-compliant NFC reader/writer functionality with Arduino UNO R3 connector compatibility, integrated LEDs, and scalable multi-board cascading capability for rapid prototyping of contactless identification systems.

Technical Context

The board implements dual NFC transceiver support-CR95HF and ST25R95-both providing full analog front-end functions including 13.56 MHz RF generation, modulation/demodulation, and protocol framing for Reader/Writer mode. Each IC embeds tag detection logic and low-power modes such as wake-on-field.

Host interface is implemented through dedicated SPI (MISO/MOSI/SCK/CS) and UART (TX/RX) lines, mapped to STM32 Nucleo GPIOs and shared with IRQ signaling. The antenna matching network includes discrete inductors (L1–L5), capacitors (C1–C17), and ferrite filters (FL1, ST1, ST2) tuned for optimal 13.56 MHz coupling and EMI suppression.

Key Specifications

Parameter	Value and Actual Design Meaning
NFC Standards	ISO/IEC 14443 A & B, 15693 (single/dual subcarrier), 18092, MIFARE Classic compatible - enables interoperability with most commercial NFC tags and cards.
Operating Frequency	13.56 MHz - fixed carrier frequency required for NFC Forum compliance and global regulatory acceptance.
Antenna	47 mm × 34 mm, 4-turn etched PCB loop - provides ~5 cm read range with standard NFC tags and eliminates need for external antenna assembly.
Host Interface	SPI Slave + UART - dual communication paths allow flexible integration with STM32 MCUs; SPI used for high-speed command/data transfer, UART for debug and interrupt-driven operation.
Regulatory Certifications	FCC ID YCPNFC03A1, IC ID 8976A-NFC03A1 - certifies legal operation in North America without additional RF testing by end users.
Physical Format	Arduino UNO R3 footprint - ensures mechanical and electrical compatibility with all STM32 Nucleo boards and third-party shields using same pinout.
LED Indicators	Four user-controllable LEDs (MCU_LED1–4) - provide real-time visual feedback for power, IRQ status, and custom firmware states during development.

FAQ

Does X-NUCLEO-NFC03A1 support both CR95HF and ST25R95 simultaneously?

No. The board is designed to operate with either the CR95HF or ST25R95 IC-not both concurrently. Hardware jumpers and firmware configuration determine which transceiver is active; ST provides separate initialization routines and driver libraries for each device in the STM32Cube expansion package.

What is the maximum reliable read distance achievable with the onboard antenna?

Under typical conditions with ISO/IEC 14443 Type A cards (e.g., MIFARE Classic), the board achieves up to 5 cm read range. Performance depends on tag size, orientation, and environmental RF noise; the 4-turn PCB antenna is optimized for balanced sensitivity and near-field coupling, not extended range.

Is external power required, or does it draw power solely from the Nucleo board?

The X-NUCLEO-NFC03A1 draws all operating power (3.3 V) from the connected STM32 Nucleo board via the Arduino UNO R3 connector. No external power supply is needed, and the board includes local decoupling (C1–C7) and filtering (FL1, ST1, ST2) to maintain stable RF performance under MCU load variations.

Can multiple X-NUCLEO-NFC03A1 boards be stacked on one Nucleo board?

Yes-ST explicitly documents cascading support via dedicated SPI chip select lines and configurable UART routing. Each board requires unique CS pin assignment and firmware-level arbitration; the hardware design includes unpopulated resistor pads (R5–R17) to isolate SPI signals when stacking, enabling multi-reader configurations for multi-zone access systems.
