The EVAL-ST95HF kit is created to evaluate the features of ST95HF.

This component is a 13.56 MHz near field communication transceiver featuring two modes, Tag emulation and NFC Reader, making it possible the use of two ST95HF evaluation boards face to face.

The EVAL-ST95HF board is powered through the USB bus. It consists of a ST95HF transceiver on a 47 mm x 34 mm, four turns 13.56 MHz inductive etched antenna and its associated tuning circuit components. The ST95HF communicates with the STM32F103RGT6 and the LCD screen via an SPI bus.

In Tag emulation mode it can be used with an NFC Reader (NFC smartphone, CR95HF or with another ST95HF) to exchange NDEF messages (URI, VCARD, URL). Communication protocol is based on ISO/IEC 14443 Type A.

In reader mode the ST95HF supports ISO/IEC 14443 Type A and B communications, ISO/IEC 15693 and ISO/IEC 18092 protocols.

The mode can be selected on screen by using a joystick.
