PayRange BluKey Module
User Manual
Introduction
The turnkey PayRange payment system includes several BluKey hardware devices for making payments
with a mobile app. Consumers maintain a prepaid balance on their smartphones and use it to make
payments at a variety of machines that can include vending, amusement, parking, transit ticketing, and
laundry equipment.
BluKey Module (BK Module) provides BluKey in a form factor suitable for easy integration into latest
generation of controller boards of vending and other kinds of machines that accept payments. It
provides a low-cost additional BOM for controller board and easy future upgrade path without redesign
of the controller board.
BK Module is implemented in a form factor and complies with mini PCI Express board standard (halfsize), so existing low-cost connectors and holders can be used, though it does not use PCI bus and
instead uses lower-end interfaces for easier software integration. Typically there is no change to the
software needed (if integration is performed using UART lines for MDB).
Usage
Usage selection requires software support from Payrange application. See Payrange.com for details.
I2C
The Blukey Module can control numerous I/Os through the I2C interface. Connect one or more
port expander circuits.
UART
The Blukey Module can communicate with a host over USB or UART using the Payrange Host
Protocol Version 1.0
Logic
The Blukey module can use its own internal GPIO to control payment devices such to imitate a
coin switch.

Notes:
Host should provide +3.3V power in low power / stand-by / suspend state.
Host may not provide +1.5V power in the low power state. BK Module does not use +1.5V.
Host must provide I2C pullups (can be to +3.3V or 5V). BK Module is a master, but it is capable of
5V I/O on I2C Bus.
Blue and Red LEDs, if implemented, should be co-located (preferably in a single device), as BK
Module may use the combination color (Magenta).
Mechanical
BK Module dimensions are the same as standard mini PCI Express half-size card, see below (RF
connector and antenna are not shown).
BluKey Module User Manual.docx 4 5/10/2016 11:09 AM
System Integration
BK Module should be placed optimally with regard to RF performance of its antenna. BK Module should
be placed so that its antenna area is near the edge of the controller board and is not obstructed by
metal and conductive parts, shields and cables.
BK Module connector requires connection to GND and 3.3V power supply and logical connection to CPU
on the controller board.
There are few ways to connect BK Module to the CPU on the controller board, with #1 being the
recommended method:
1. Use UART (3.3V domain signals)
2. Use SMB Bus (or I2C bus). This method requires special BK Module firmware.
3. Use USB bus. This method requires BK Module with USB option.
The above connections are sufficient to fully enable BK Module for operation in PayRange system. Few
other options are provided for further level of integration:
A. BK Module RF Interface – Internal Bluetooth antenna. The RF connector is only intended for
manufacturing test.
B. BK Module User interface – LEDs and button. If mechanical integration blocks service access to
BK Module LEDs and / or button, controller board may provide LEDs and/or button to mirror BK
Module indication and replacement button control.
BluKey Module User Manual.docx 5 5/10/2016 11:09 AM
C. Aux UART – BK Module with slave port option can support secondary devices (e.g. credit card
reader interface).
D. BK Module reset. If controller board should be able to reset its peripherals (e.g. for entering
service mode without power cycle), BK Module reset should be connected to controller board
reset line.
E. BK Module radio disable. If controller board should be able to disable all RF transmissions, BK
Module radio disable should be connected to corresponding controller board line. An alternative
soft command could be defined in customized BK Module firmware.
F. GPIO lines – for custom functionality (e.g. mechanical controls, or coin collector counter), BK
Module can support additional functions with customized firmware.
G. I2C interface – additional peripherals can be accessed by BK Module with customized firmware.
Please inquire with PayRange support for custom options.
United States FCC Requirements
Labeling
The BK Module has been labeled with its own FCC ID number, and if the FCC ID is not visible when the
module is installed inside another device, then the outside of the finished product into which the
module is installed must also display a label referring to the enclosed module. This exterior label can use
wording as follows:
Contains Transmitter Module FCC ID: 2AF78-00370 or Contains FCC ID: 2AF78-00370
User Manual
The User Manual must contain the following:
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 This equipment has been tested and found to comply with the limits for a
Class B digital device, pursuant to part 15 of the FCC Rules.
These limits are designed to provide reasonable protection against harmful interference in a
residential installation. This equipment generates, uses and can radiate radio frequency energy,
and if not installed and used in accordance with the instructions, may cause harmful
interference to radio communications. However, there is no guarantee that interference will not
occur in a particular installation. If this equipment does cause harmful interference to radio or
television reception, which can be determined by turning the equipment off and on, the user is
encouraged to try to correct the interference by one or more of the following measures:
• Reorient or relocate the receiving antenna.
• Increase the separation between the equipment and receiver.
BluKey Module User Manual.docx 6 5/10/2016 11:09 AM
• Connect the equipment into an outlet on a circuit different from that to which the receiver is
connected.
• Consult the dealer or an experienced radio/TV technician for help.
CAUTION: Per FCC 15.21, changes or modifications not expressly approved by the party
responsible for compliance could void the user's authority to operate the equipment.
RF EXPOSURE
The BluKey Module is certified as a modular transmitter device for integration into fixed products under
the following conditions:
1. The antenna(s) must be installed such that a minimum separation distance of 20cm is
maintained between the radiator (antenna) and all persons at all times.
2. The transmitter module must not be co-located or operating in conjunction with any other
antenna or transmitter.
As long as the two conditions above are met, further transmitter testing will not be required. However,
the OEM integrator is still responsible for testing their end-product for any additional compliance
requirements required with this module installed (for example, digital device emissions, PC peripheral
requirements, etc.). IMPORTANT NOTE: In the event that these conditions cannot be met (for certain
configurations or co-location with another transmitter), then the FCC and Industry Canada
authorizations are no longer considered valid and the FCC ID and IC Certification Number cannot be
used on the final product. In these circumstances, the OEM integrator will be responsible for reevaluating the end product (including the transmitter) and obtaining a separate FCC and Industry
Canada authorization.
