PN7160 evaluation board
2 Introduction
The present document describes the OM27160 evaluation board, a flexible and easy-to-
use NFC controller board featuring PN7160.
It enables the development of an NFC solution based on PN7160 in a Linux or Android
environment or even in system based on RTOS or without OS.
It exists in 2 configurations, the only difference is then physical host interface exposed:
•OM27160A1HN featuring PN7160A1HN sample offering I2C host interface
•OM27160B1HN featuring PN7160B1HN sample offering SPI host interface
This document presents first an overview of the board, then it gives printed circuit boards
details, and finally it provides information for reuse of the kit in different environments.
IMPORTANT NOTICE
For engineering development or evaluation purposes only
NXP provides the product under the following conditions:
This evaluation kit is for use of ENGINEERING DEVELOPMENT OR
EVALUATION PURPOSES ONLY. It is provided as a sample IC pre-
soldered to a printed-circuit board to make it easier to access inputs,
outputs and supply terminals. This evaluation board may be used with any
development system or other source of I/O signals by connecting it to the
host MCU computer board via off-the-shelf cables. This evaluation board
is not a Reference Design and is not intended to represent a final design
recommendation for any particular application. Final device in an application
heavily depends on proper printed-circuit board layout and heat sinking
design as well as attention to supply filtering, transient suppression, and I/O
signal quality.
The product provided may not be complete in terms of required design,
marketing, and or manufacturing related protective considerations, including
product safety measures typically found in the end device incorporating the
product. Due to the open construction of the product, it is the responsibility of
the user to take all appropriate precautions for electric discharge. In order to
minimize risks associated with the customers’ applications, adequate design
and operating safeguards must be provided by the customer to minimize
inherent or procedural hazards. For any safety concerns, contact NXP sales
and technical support services.

3 OM27160 board overview
The OM27160 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 40 mm * 40 mm 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 (see [1]).

5 Additional information
5.1 Using different I2C address
The OM27160A1HN board come with default 0x28 (7 bits) I2C PN7160 slave address.
However, it is still possible to change it (between 0x28 and 0x2B) by setting of R10, R11,
R12 and R13 resistors.

5.2 Using in another system
The OM27160 board can be reuse in another system (different from Raspberry Pi or
BeagleBone, and not offering Arduino compatible interface). Indeed, the board provides
all required signals on J1, J2, J3 and J4 connectors to interface any host device.
