NFC Nutshell NFC Modules
General Topology
The Kit consists of different types of modules, which can be connected application specific. Each
module type has a different color.
•Interface
•MCU
•NFC
•Antenna
Fig 1. Kit modules and PCB solder mask color coding
Module interconnection concept
The Nutshell Kit can be operated in different configurations. The connection between the different
modules is done via FFC cables and zero force sockets.
Fig 2. Kit modules interconnection via FFC cables
For ensuring a proper connection the cable must be inserted straight at any time

The Kit modules can be connected to a host via different interface modules see details in the NFC
Nutshell Kit interface module user manual.
Important Notes:
•Open and close the connector carefully
•Always insert straight –do not apply force
•Avoid cable/connector misalignment –potential short cut and damage
•If you observe communication issues over time, exchange the FFC cable with a spare one
•DO NOT disconnect, bend or move the Kit while modules are powered to avoid short circuits
Module Connector Signal pin-out
The following figure describes the signal which can be analyzed using the Extender module.
Detailed information can be found in the user manual of the interface modules.
Fig 4. Module Zero Force FFC Connector Signal Pinout
Module power concept
The Kit requires a power supply of +5V DC. This can be applied using one of the following options:
•Using one of the interface module
oUSB supply voltage (4.75V to 5.25 V) is available on all connected modules using the
USB plug.
•Using an external power supply and the Signal extender module
o+5V is required
If other voltages than 5V are needed by the module, this is generated onboard with an LDO.
Important Note:
If using an external power supply, ensure the correct amplitude and polarity before power up of the
Kit.

NFC Module hardware topology
The topology of the NFC modules is shown next:
Fig 6. NFC Module interface MCU/HOST interface, power and antenna connection
As can be seen above, the NFC frontends are connected to the MCU via SPI interface. This
allows the user to operate with the maximum performance.
The modules also features the EMC filter which is necessarily close to the output of the NFC
front end. The modules also only require a single 5V supply. All other voltages are generated
on the module.
Note: 3 pin antenna connection is symmetrical with no preferred direction

Standard Kit configuration
The primary use case of the NFC modules is shown next. The MCU is connected to one frontend
using the FFC cable.
Fig 7. PC –Standard connection Interface - MCU- NFC
In this configuration the firmware of the MCU module implements the whole protocol
handling. The communication is realized using SPI interface, IRQ and Reset control lines.
This topology allows to easily exchange different NFC frontends.
PC –NFC Direct Communication Mode
Besides using the Kit with an MCU Module connected, there is the possibility to connect the
Modules directly.
This mode allows an easy implementation using the PC as direct communication interface.
Fig 8. PC - NFC direct execution
For using the KIT without any MCU the kit has to be connected as shown above. Using the
Protocol Converter Tool, the user has to choose the NFC Direct mode.
This changes the NFC interface to UART and allows easy access to the NFC front end using
the converter module as USB to UART converter.

Use of the NXP Reader Library and Microsoft Visual Studio
For further development, the export controlled version of the NXP reader library can be
used. This version features C++ based projects which can be used to communicate with the
front end.
Important Note:
This works only with the export controlled version of the NXP reader library. A valid NXP Doc
store account and access is needed.
More details can be found in the Interface User Manual of the Protocol Converter Module.
Use Direct Mode with RFID Discover
It is also possible to run the RFIDDiscover with the CLRC663 in UART Mode. The USB Protocol
Converter must be set in the PC direct mode (white LED glowing) in order to be used with
RFIDDiscover.
Fig 9. PC –CLRC663 COM reader direct PC connection setup with RFIDDiscover
Note: The reaction of the CLRC663 is slower when operated in this mode via COM port.

NFC Module Antenna connection
Different antennas are available which can be easily connected to the NFC Nutshell kit using a
twisted 30cm 3 wire cable which is shown next.
Fig 10. NFC Module –NFC Antenna connection
The matching of each antenna is optimized for using with all different featured NFC Modules.
Note: 3 pin antenna connection is symmetrical with no preferred direction
