The GEM 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 module is based on Nordic Semicondutor’s nRF51422 dual band Bluetooth and ANT+ chipset. The GEM 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 -‐93dBm. This manual is intended to assist hardware integration of the GEM module into a given design. Details on Wahoo’s Fitness Machine software can be found in the GEM module Fitness Machine Software guide. For applications using Nordic Semiconductor SDK, please refer to Nordic Semiconductor’s SDK available at developer.nordicsemi.com.

The following section provides suggestions to ensure successful design in of the GEM module. Hardware VCC Ensure the power source operating range and noise is within the specified limits for the GEM module and filter capacitors are incorporated as needed. The GEM 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 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 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 module over the air: Wahoo Fitness 90 West Wieuca Road, Suite 110 Atlanta, GA 30342 www.wahoofitness.com 1-‐877-‐978-‐1112 GEM Module Hardware Integration Guide Version 0.3 Example for Serial Wire Debug Interface UART Host The UART is required for communicating between the GEM module and fitness machine console using the CSAFE protocol. Pins 15 and 16 of the module have been configured as the UART interface. Pin 15 is the UART TX line and pin 16 is the UART RX line. Reset The GEM module can be reset by holding PIN 22 low for 0.5us. The following is an example reset circuit: Example Reset Circuit Wahoo Fitness 90 West Wieuca Road, Suite 110 Atlanta, GA 30342 www.wahoofitness.com 1-‐877-‐978-‐1112 10 GEM Module Hardware Integration Guide Version 0.3 Module Layout Considerations General Considerations 1. Locate the GEM Module close to the edge of your circuit board for best RF performance. 2. A solid ground plane should be used except for the antenna keep-‐out area. 3. All module GND pins must be connected to your circuit ground. 4. Place GND vias close to the module GND pads 5. Route traces to avoid noise being picked up on VCC or I/O lines 6. Ensure no exposed copper is located underneath the GEM module Top-‐side area directly under the module should be kept clear of copper, silkscreen and vias Antenna Considerations The GEM antenna was characterized using the GEM development board. Similar performance can be obtained by following the following layout guidelines: 1. Locate the GEMSRB01 on the edge of the host PCB in the right corner to allow the antenna to radiate properly. 2. Keep all mounting hardware and metal clear of the keep out area for proper antenna radiation. 3. Metal close to the GEMSRB01antenna will have degradation on the antenna performance. Suggested clearances are 20mm top/bottom and 20mm left or right. 4. It is best that the customer test with an actual prototype or final design to see the effects of any enclosure. 5. The antenna keep-‐out area and dimensions are shown in the figure below. Antenna Characteristics The GEM module includes an integrated monopole chip antenna. Antenna performance will depend on host PCB layout. The following plots show antenna radiation pattern of the GEM antenna.
