　　PN7150 NFC控制器单板计算机(SBC)套件

　　The present document describes the OM5578/PN7150S demonstration kit, a flexible and easy-to-use Single Board Computer (SBC) Kit for the PN7150 NFC Controller.

　　It enables the development of an NFC solution based on PN7150 in a Linux, Android or Windows for IoT environment or even in system based on RTOS or without OS.

　　It exists in different configurations:

　　- OM5578/PN7150RPI to be used with Raspberry Pi platform (see [1])

　　- OM5578/PN7150BBB to be used with BeagleBone Interface Board (see [2])

　　- OM5578/PN7150ARD to be used with platforms offering Arduino compatible interface (see [3]), like LPCXpresso (see [5]) or Kinetis Freedom (see [4]).

　　All 3 OM5578 kits contains a PN7150 NFC Controller Board, a dedicated interface board, as well as an NFC Sample Card in form of an NFC Forum Type 2 Tag.

　　The OM5578 PN7150 NFC Controller Board is high performance fully NFC compliant expansion board, meeting compliance with Reader mode, P2P mode and Card emulation mode standards.

　　The board features an integrated high performance RF antenna to insure high interoperability level with NFC devices.

　　It has to be used in association with one interface board according to the targeted user environment. For this purpose it integrates the NFC generic interface allowing assembly with OM29110 Interface boards.

　　The Generic NFC interface exposes Single-Board-Computer physical interfaces required by the NFC’s boards. Those are:

　　- Usual power supplies (3.3V, 5.0V)

　　- Usual IC interfaces (I²C, SPI, UART)

　　- Generic GPIOs (can be used for different purposes depending on IC feature (field detect, interrupt, reset...)

　　The BeagleBone Interface Board offers support for connection to BeagleBone board.

　　As such it integrate the NFC generic interface connectors allowing NFC’s board to be plugged on it, as well as connectors to be assembled on top of the BeagleBone board.

　　The Arduino Interface board offers support for connection to any SBC board implementing ArduinoTM connectors compatible with the ’Arduino UNO’ platform.

　　As such it integrate the NFC generic interface connectors allowing NFC’s board to be plugged on it, as well as connectors to be assembled on top of an Arduino compatible Controller board like for instance LPC824 MAX LPCXpresso board.

　　The board include a R1 footprint between the VOUT pin of the NFC Generic connector and the VIN pin of the Arduino connector. The purpose of it is to allow powering the Arduino compatible platform from the NFC Board in case both support it.
