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: Wahoo Fitness 8 90 West Wieuca Road, Suite 110 Atlanta, GA 30342 www.wahoofitness.com 1‐877‐978‐1112

GEM 2 Module Hardware Integration Guide Version 0.1 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.

GEM 2 Module Hardware Integration Guide 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 Wahoo Fitness 10 90 West Wieuca Road, Suite 110 Atlanta, GA 30342 www.wahoofitness.com 1‐877‐978‐1112

GEM 2 Module Hardware Integration Guide 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. French equivalent: Le présent appareil est conforme aux CNR d'Industrie Canada applicable aux appareils radio exempts de licence.

IC Radiation Exposure Statement This device is in compliance with SAR for general population/uncontrolled exposure limits in IC RSS‐102 and had been tested in accordance with the measurement methods and procedures specified in IEEE 1528. REMARQUE IMPORTANTE Déclaration IC d'exposition aux radiations Ce EUT est conforme avec SAR pour la population générale / limites d'exposition non contrôlée à IC RSS‐102 et a été testé en conformité avec les méthodes de mesure et procédures spécifiées dans la norme IEEE 1528. 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 2 Module Contient des IC: TBD" Wahoo Fitness 15 90 West Wieuca Road, Suite 110 Atlanta, GA 30342 www.wahoofitness.com 1‐877‐978‐1112
