Swish-Hoop Net Sensor Module Integration Manual v1.2 2017 Shooters Touch, LLC 25 Rolling Lane Weston, MA 02493 CONFIDENTIAL 1-781-354-3354 steve@swishhoop.com www.SwishHoop.com 1 Preface The following guidelines must be followed when integrating the Swish-Hoop Net Sensor Module

(SHNSM) into other devices. This manual describes the methods for integration of hardware, software and documentation. 2 Typical Use and Product Variants The Swish-Hoop Net Sensor module (SHNSM) is intended to be used in a number of different electronic products manufactured by Shooters Touch, LLC and others. The following is a subset of functions for some of the products:

Swish-Hoop Shot Monitor The SHNSM is connected to a CR2477 coin cell battery and housed in a plastic enclosure. The enclosed device is then hung on a basketball net that is attached to the goal and the systems function is to sense and record makes and misses. The vibration switch and tilt switch are used to sense interactions between the basketball and the rim, net or backboard and the radio on the SHNSM is used to transfer the data to a connected mobile device. The radio is also used to send status information and software updates back and forth. Swish-Hoop Personal Scoreboard The SHNSM is connected to a main display board by soldering pins extending from the main display board to the through holes on the SHNSM. A rechargeable battery on the main display board delivers power to the SHNSM. The SHNSM microprocessor outputs are connected to a set of LED drivers on the main display board to create messages. The radio on the SHNSM is used to transfer message data from mobile device that is to be displayed. The radio is also used to send status information and software updates back and forth. Swish-Hoop Rim The SHNSM is connected to a main motor board by soldering pins extending from the main motor board to the through holes on the SHNSM. A rechargeable battery on the main motor board delivers power to the SHNSM. The SHNSM microprocessor outputs are connected to a motor driver and sensors on the main motor board to actuate the rim. The radio on the SHNSM is used to transfer data from mobile device that drives the motor on the rim. The radio is also used to send status information and software updates back and forth. 3 Hardware The SHNSM is designed for soldering either onto a battery or directly into another circuit board for the target application. Standard JDEC-PCB-free reflow soldering temperature profiles apply. Detailed schematic layouts and other documents are available upon request. No antenna except the one integrated into the SHNSM circuit board shall be used. 3.1 Physical Description The SHNSM is 25 X 25 X 5 mm including all components. The board thickness without components is 1 mm. 3.2 Components The SHNSM uses a Nordic Semiconductor nRF51822 microprocessor with two clock inputs at 16 MHz and 32.768 KHz. The nRF microprocessor includes the drivers for a 2.4GHz radio transceiver. In addition to the microprocessor and its associate components, the SHNSM includes an omnidirectional vibration switch and tilt switch, which is closed when the antenna end of the board is pointed down and open otherwise. Three pins on the SHNSM are supplied for Segger J-Link device connection to the microprocessor. 3.3 Operating Specifications 3.3.1 Input Power 3VDC, 10 microamps most of the time, 150 mA for 150mSec every 1 second 3.3.2 Operating temperature range of the equipment Outdoor commercial temp range - 0 to 70 degrees Celsius 3.3.3 Classification Portable 3.3.4 Number and types of i/o ports and associated cables 30 ports on CPU, no cables

(channel 39) Remainder are Data channels (channels 0 - 36) 3.3.5.3 Type of Transmit: Frequency hopping, spread spectrum / digital modulation system / fixed To mitigate interference in such a crowded band, BLE uses frequency hopping. Three RF channels are dedicated for advertising functions that allow the discovery of devices available in the vicinity. Upon a connection request, the same channels are used for initial connection parameter exchanges. Once a device is discovered and connection is initiated, regular data channels are used for communication 3.3.5.4 Transmitter Power output 0 dB 3.3.5.5 Antenna type PCB trace No other antenna shall be used. 3.3.5.6 Transmission Duty cycle While advertising, every second or so While in regular mode (after connection) whenever data needs to be sent Every second it sends out battery information (a few bytes of payload) 3.3.5.7 Device Duty cycle Sleeps most of the time Wakes up every 100mSec or so to keep BT connection alive Wakes up asynchronously when event(s) happen as part of device function Mounting 3.4 For best RF performance, place the SHNSM at the edge of the target board with a margin beyond the target board as shown below. 5mm MIN 5mm MIN ANTENNA SHNSM 5mm MIN ANTENNA SHNSM TARGET BOARD TARGET BOARD Keep any metal parts at least 10mm from the antenna area of the SHNSM board. 4 Software The SHNSM firmware consists of three portions: the Bootloader, the BLE SoftDevice and the application firmware. The Bootloader and the BLE SoftDevice are provided by the microprocessor chip producer, Nordic Semiconductor (www.nordicsemi.com). The application software is specific to the application. It monitors the sensor outputs on the SHNSM and sends and receives BLE messages using the SoftDevice. The Bootloader may be used for DFU OTA (Device Firmware Update Over The Air) application software updates using the nRF Toolbox app on a mobile device or custom software. Firmware application software updates may also be performed using Segger J-Link device connected to the three pins on the SHNSM. 5 Regulatory Statements 5.1 FCC Statement This device has been tested and found to comply with 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 the receiver 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. Operation is subjected to the following two conditions: (1) This device may no cause harmful interference, and (2) this device must accept any interference received, including interference that may cause undesired operation. Note: Modification to this product will void the users authority to operate this equipment. Note: Modification to this product will void the users authority to operate this equipment. 5.2 FCC Important Notes:

5.2.1 FCC Radiation Exposure Statement This equipment complies with FCC RF radiation exposure limits set forth for an uncontrolled environment.
