GEM 2 Module Hardware Integration Guide
Version 0.1
Overview and Key Features
The GEM module has been designed to allow OEMs to easily add Bluetooth and ANT+
wireless connectivity in their product offering. The GEM 2 module incorporates Wahoo
Fitness software specifically designed to enable fitness machines such as treadmills,
exercise bikes, ellipticals, rowers, stair climbers and step machines to wirelessly
communicate exercise data with smart phone or tablets as well as leaderboard software
systems. For applications other than fitness machines, developer’s can use Nordic
Semiconductor’s SDK to create their own embedded application specific software.
The GEM 2 module is based on Nordic Semicondutor’s nRF52832 multiprotocol Bluetooth
and ANT+ chipset. The GEM 2 module offers a variety of peripheral interfaces including
UART, SPI, I2C, ADC, and GPIO, has a maximum transmit power of +4dBm, and a sensitivity
of ‐96dBm. This manual is intended to assist hardware integration of the GEM 2 module
into a given design. Details on Wahoo’s GEMSAFE and GEMHCI software can be found
www.wahoogy.com. For applications using Nordic Semiconductor SDK, please refer to
Nordic Semiconductor’s SDK available at developer.nordicsemi.com.

Design Considerations
The GEM 2 module has been designed for easy integration into OEM applications requiring
minimal additional componentry. The following section provides suggestions to ensure
successful design in of the GEM 2 module.
Hardware
VCC
Ensure the power source operating range and noise is within the specified limits for the
GEM 2 module and filter capacitors are incorporated as needed. The GEM 2 module
includes decoupling capacitors for circuits within the module. External circuits sharing the
same power source should also be decoupled locally at connections to VCC and GND.
Updating Module Firmware
The GEM 2 module firmware can be updated over the air using the Wahoo utility
application. The Wahoo utility application can be downloaded here: www.xxxx.yyy.com
The GEM 2 module firmware can also be updated through the Serial Wire Debug interface.
The following circuit example provides a reference for developers wanting an alternative to
programming the GEM 2 module over the air:

Example for Serial Wire Debug Interface
UART Host
The UART is required for communicating between the GEM 2 module and fitness machine
console using the GEMSAFE or HCI command protocol. Pins 13 and 14 of the module have
been configured as the UART interface. Pin 13 is the UART TX line and pin 14 is the UART
RX line.
Reset
The GEM 2 module can be reset by holding PIN 25 low for 0.5us. The following is an
example reset circuit:

Version 0.1
Module Layout Considerations
1. Good: Place module antenna side as close as possible to the board edge. Better:
Allow module antenna area to overhang the edge of the board by ~5.6mm.
2. Good: Define a copper keepout area approx. 53mm x 20mm, 6mm in from module
edge. Better: Increase the keepout area, starting at 6mm in from module edge.
3. Mechanical items (especially metal) should be kept as far as possible from the
module antenna in all directions, including above and below the board surface. If
possible, move mechanical items out and away from the keepout area.
4. Bottom layer ground plane under the module strongly recommended. Connect all
ground pins directly to ground plane.
5. Top layer ground plane is good to have wherever practical, but avoid having copper
directly under the module.
6. Place Via stitching where both top and bottom layer ground planes are used,
especially along the plane edges adjacent the module.
Top‐side area directly under the module should be kept clear of copper, silkscreen and
vias

Regulatory & Standards Information
FCC & Industry Canada
The GEM 2 module has modular approval for the United States and Canada. To ensure
compliance when using the GEM 2 module in a design, the OEM is required to adhere to the
implementation considerations supplied in this hardware integration guide.
Federal Communication Commission (FCC) Radiation Exposure Statement:
This device is in compliance with SAR for general population/uncontrolled exposure limits
in ANSI/IEEE C95.1‐1999 and had been tested in accordance with the measurement
methods and procedures specified in OET Bulletin 65 Supplement C.
This transceiver must not be co‐located or operating in conjunction with any other antenna,
transmitter, or external amplifiers. Further testing / evaluation of the end product will be
required if the OEM’s device violates any of these requirements.
The GEM 2 Module is fully approved for mobile and portable applications.
FCC Labeling Requirements
WARNING: The OEM must ensure that FCC labeling requirements are met. This includes a
clearly visible label on the outside of the OEM enclosure specifying the appropriate FCC
identifier is visible.
Contains
FCC ID: PADWF116
IC: 10563A‐WF116
If OEM device is larger than 8x10cm, the following FCC part 15.19 statement has to be
visible on outside of device:
The enclosed 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

Version 0.1
Label and text information type should be large enough to be legible and consistent with the
dimensions of the equipment and the label. The type size is not required to be larger than
eight points.
Comments
The OEM should have their device tested by a qualified test house to verify compliance with
FCC Part 15 Subpart B limits for unintentional radiators.
Any modifications to the GEM 2 module could void the OEM’s authority to operate the
equipment.
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 not cause harmful interference to radio or
television reception, which can be determined by turning the equipment off and on, the user
is encouraged to correct the interference by one or more of the following measures:
 Re‐orient or relocate the receiving antenna
 Increase the separation between the equipment and the receiver
 Connect the equipment to an outlet on a circuit that is different from that to which
the receiver is connected.
 Consult the dealer or an experienced radio/TV technician for help.
FCC Warning:
“THIS DEVICE COMPLIES WITH PART 15 OF THE FCC RULES AND INDUSTRY CANADA
LICENSE‐EXEMPT RSS STANDARD(S). 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.
Industry Canada (IC) Warning:
This device complies with Industry Canada license‐exempt RSS standard(s). Operation is
subject to the following two conditions: (1) this device may not cause interference, and (2)
this device must accept any interference, including interference that may cause undesired
operation of the device.

Modular Approval
OEM is still responsible for testing their product for any additional compliance
requirements required with this module installed (for example, digital device emissions, PC
peripheral requirements, etc.).
Approbation modulaire
OEM intégrateur est toujours responsable de tester leur produit final pour les exigences de
conformité supplémentaires nécessaires à ce module installé (par exemple, les émissions de
périphériques numériques, les exigences de périphériques PC, etc.)
IMPORTANT NOTE:
In the event that these conditions cannot be met (for example certain laptop configurations
or co‐location with another transmitter), then the Canada authorization is no longer
considered valid and the IC ID cannot be used on the final product. In these circumstances,
the OEM integrator will be responsible for re‐evaluating the end product (including the
transmitter) and obtaining a separate Canadian authorization.
NOTE IMPORTANTE:
Dans le cas où ces conditions ne peuvent être satisfaites (par exemple pour certaines
configurations d'ordinateur portable ou de certaines co‐localisation avec un autre
émetteur), l'autorisation du Canada n'est plus considéré comme valide et l'ID IC ne peut pas
être utilisé sur le produit final. Dans ces circonstances, l'intégrateur OEM sera chargé de
réévaluer le produit final (y compris l'émetteur) et l'obtention d'une autorisation distincte
au Canada.
Le produit final doit être étiqueté dans un endroit visible avec l'inscription suivante: " GEM
