1. General Information / Security Advice
1.1. Notes on the Use of this Documentation
This user manual and integration guide uses different symbols to point out potentially
dangerous situations. The following signs and symbols are used throughout the document.
ATTENTION
Declares a potentially hazardous situation. If this is not avoided, the product
or something in its surrounding could be damaged.
NOTES
Declares notes for the user as well as other useful information, where no
harmful or dangerous situations can be expected.
1.2. Export Restriction
The QR15 HF RFID Module contains components that underly US export restrictions. It is
therefore forbidden to export the product to countries that are on the US trade embargo
list.
1.3. Further Documentation
While this documentation explains the electrical and mechanical characteristics of the QR15
module, it might be useful to also read the metraTec Protocol Guide, which explains the
ASCII protocols used to control the module in full detail.

2. Product Description
The QR15 HF RFID Module is an easy to use RFID module which can be integrated into your
electronics without big effort. This allows you to equip your product with RFID functionality
without designing your own RF board. Thanks to the tested and extremely flexible firmware
you can read and write data to any tag that follows the ISO 15693 standard in no time. Even
special features, e.g. sensor tags, can be used without firmware modifications. With its
internal antenna a read range of up to 80mm is possible.
Thanks to the quick firmware, the module is perfect for applications in printers and similar
devices where high reading and writing speed is needed.
2.1. Intended Use
The QR15 HF RFID Module reads RFID tags that comply to the ISO 15693 standard on a
short range of 30-80 mm. Custom tag commands can be used without firmware changes if
the tags follow the ISO 15693 standard with regard to the air interface. For transponders
that use the ISO 14443A or Mifare standard, please use our QR14 RFID Module.
2.2. Technical Specification
Power Supply 5V DC, 100 mA
Communication 5V UART
Antenna Connector Internal Antenna
Transmit frequency 13.56 MHz
RF output power 250 mW
Supported RFID Protocol ISO 15693
Temperature Range -20°C to +70°C
Dimensions 51 x 51 mm (2” x 2”)
2.3. Module Building Blocks
The QR15 module consists of four building blocks, each of them carrying out one of the
following functions:
•UART-communication and power supply – host communication via 5V UART and
5V power supply are connected to the host board via pin
•Microcontroller – the heart of the QR15 running the metraTec firmware

•RF Frontend – generates the signal transmitted to the tag and evaluates the Tag
response
•Internal antenna – the internal 50mm x 50mm antenna can achieve reading
distances up to 80mm

3. Power Supply and Power Consumption
The module does not feature a power supply nor reverse polarity protection. It is the task of
the host board to supply a well filtered 5V DC supply in order to achieve an optimum RFID
performance.
Pin Pin Function
X1.1 GND
X1.2 5V DC
Tab. 1: Power Supply Pins
Power supply voltage 5V DC
Current consumption RF on 100 mA
Current consumption RF off 20 mA
GPIO voltage level 5V
Tab. 2: DC characteristics
RFID systems require a very high level supply quality. Use linear regulators with high
precision and high control speed whenever possible. When using switching power supplies
make sure the switching speed is above 500 kHz and us an EMC optimized layout as well as
shielded inductors.

4. Communication
Das QR15 HF RFID Module communicates with its host using a 5V UART connection. This
enables direct connection to a host microcontroller. There is a range of circuits available to
convert the 5V UART Signal to RS232, RS422/485 or to USB or Ethernet. Please contact
metraTec if you need advice on such converter circuits.
Pin Pin Function
X2.1 GND
X2.2 Tx
X2.3 Rx
Tab. 3: UART Pin connections
The UART commands used to control the QR15 Module are described in the metraTec
Protocol Guide. This guide comprises a detailed description of all commands, response
formats and examples. As this protocol is shared among several metraTec products the
guide is available in a separate document.

5. Certification
5.1. FCC (USA)
The QR15 HF RFID Module complies with Part 15 of the FCC Rules. To fulfill all FCC
requirements the Original Equipment Manufacturer (OEM) must comply with the following
regulations:
–The OEM must make sure that the end device is labeled according to FCC
requirements. This means that the end device must have a clearly visible label on
the outside of the product with at least the following content:
Contains FCC ID: YUH-QR15HL
This device complies with Part 15 of the FCC Rules. Operation is subject to the
following two conditions: (1) this device may not cause harmful interference, and (2)
this device must accept any interference received, including interference that may
cause undesired operation.
–The OEM must test the final product to comply with FCC regulations regarding
unintentional radiators (FCC section 15.107 and 15.109) before declaring FCC
compliance of his own product.
ATTENTION
Changes or modifications not expressly approved by metraTec could void the
user’s authority to operate the equipment.
5.2. IC (Canada)
Labeling requirements for Industry Canada (IC) are similar to those of the FCC. A clearly
visible label on the outside of the final product must display at least the following text:
Contains Model QR15 RFID Module, IC: 9278A-QR15HL
The OEM is responsible for its product to comply with IC ICES-003 & FCC Part 15, Sub. B -
Unintentional Radiators. ICES-003 is the same as FCC Part 15 Sub. B and Industry Canada
accepts FCC test report or CISPR 22 test report for compliance with ICES-003.
