Evaluation board for ST95HF NFC transceiver

Introduction

The EVAL-ST95HF is a ready-to-use development kit used to evaluate functions and

performances of the RF transceiver ST95HF in Reader mode, Card emulation mode or Peer

to Peer Mode for standard contactless applications.

The EVAL-ST95HF kit supports:

• ISO/IEC 14443 Type A and B communication in Reader;

• ISO/IEC 15693 in Reader mode only;

• ISO/IEC 14443 Type A communication in Card emulations mode;

• ISO/IEC 18092 protocols in Reader modes.

The ST95HF also supports the detection, reading and writing of NFC Forum Type 1, 2, 3

and 4 tags.

The EVAL-ST95HF kit includes a ST95HF transceiver, a 4 turns 47 x 34 mm 13.56 MHz

inductive etched antenna and its associated tuning components, a STM32F103 32-bits

microcontroller with 1 Mbyte of Flash memory and a TFT LCD 2.4 inch and 240*230

resolution.
