2 Introduction
The present document describes the OM5577/PN7120S demonstration kit, a flexible and
easy-to-use Single Board Computer (SBC) Kit for the PN7120 NFC controller.
It contains a PN7120 NFC controller board, a Raspberry Pi interface board, a
BeagleBone interface board, as well as an NFC Forum Type 2 Tag in a form of a MIFARE
Ultralight card. It enables the development of an NFC solution based on PN7120 in a
Linux or Android environment.
In this document, the term „MIFARE Ultralight card“ refers to a MIFARE Ultralight IC-
based contactless card.
PN7120 is a full NFC controller solution with integrated firmware and NCI interface
designed for contactless communication at 13.56 MHz.
This document presents first an overview of the kit.
Then, it gives printed circuit boards details.
Finally, it provides information for reuse of the kit in different environments.
This kit is registered as FCC certified module (FCC ID: OWROM5577-PN7120S).

3 Overview
3.1 Kit description
OM5577/PN7120S kit is a high performance fully NFC-compliant expansion board for
both Raspberry Pi (refer to [1] for more details) and BeagleBone (refer to [2] for more
details). It meets 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.
3.2 Kit content
The kit is composed of 3 printed circuit boards and a MIFARE Ultralight EV1 card.

3.2.1 PN7120 NFC controller board
The PN7120 NFC controller board is the main board of the demonstration kit. It embeds
the PN7120 and all related circuitry.
It also includes an onboard RF antenna with related matching circuitry.
This main board has to be used in association with one of the 2 interface boards
depending on the target user environment (Raspberry Pi or BeagleBone).
For this purpose, it integrates dedicated connectors allowing boards assembly.

3.2.4 MIFARE Ultralight EV1 card
OM5577/PN7120S kit includes a MIFARE Ultralight EV1 card allowing to demonstrate
NFC reader capabilities of PN7120 NFC controller.
MIFARE Ultralight EV1 is the next generation of paper ticketing smart card IC for limited-
use applications. It offers solution developers and operators the maximum flexibility for
their ticketing schemes and additional security options.
For the current purpose of PN7120 NFC Controller demonstration, the card has been set
as NFC Forum Type 2 Tag, and pre-configured with NDEF URI type message “https://
