EVAL-ST95HF
Description
The EVAL-ST95HF kit is created to evaluate features of the ST-Microelectronics ST95HF.
This component is a 13.56 MHz near field communication transceiver which could be used
in two modes as well in Tag emulation as NFC Reader. So we could use two ST95HF Eval
board face to face.
The EVAL-ST95HF board is powered through the USB bus. It is consist of a ST95HF
transceiver on a 47 x 34 mm -4 turn and 13.56 MHz inductive etched antenna and its
associated tuning circuit components. The ST95HF communicates with the
STM32F103RGT6 and LCD screen via SPI bus.
In Tag emulation mode it could be used with NFC Reader (NFC smartphone, CR95HF or
with another ST95HF) to exchange NDEF messages (URI, VCARD, URL) or establish a
P2P communication. Communication protocol is based on ISO/IEC 14443 Type A.
In reader mode the ST95HF support ISO/IEC 14443 Type A and B communication, ISO/IEC
15693 and ISO/IEC 18092 protocols.
The mode could be selected on screen by using a joystick.
