Trackpad Module Datasheet V1.03 Page 3 of 20 September 2015 IQ Switch(R) ProxSense(R) Series 1.3 Module Orientation All the modules have a cut in the PCB indicating the top of the module, which could also be used to align the module on the application overlay. This Notch can be seen in Figure 1.2 Top Of Module UP *Top Tip: Make sure the module is secured to the application with the double sided adhesive tape with no air gaps to do performance evaluation. FW Down BW Figure 1.1 Top Notch Illustrating Module Orientation. 1.4 Adhesive Specification All 6 modules offered are supplied with double sided adhesive applied on the trackpad for ease of integration. The adhesive is kept with the liner kept in place, with a pull tab for easy removal without tearing: - Type: 3M 468 200MP Thickness = 0.13mm Liner = Polycoated Kraft Paper Liner w/ Pull-Tab (No glue on Pull-Tab) Adhesive sized to fit entire tracking area (module specific) 1.5 Total Thickness The total thickness given in Figure 1.2 does not include the protective liner on the adhesive, as this liner needs to be removed when the module is assembled into the application. The highest part (thickest part of the module) of the assembly is located at the 0603 capacitor - C2. Copyright (c) Azoteq (Pty) Ltd 2015. All rights reserved.

The modules have a solder link, S1, which can select one of two sensitivity settings tuned for different overlay thicknesses. Table 1.3 Module Overlay Compatibility1. Solder link S1 Overlay Range Open Closed 1mm - 2mm 2mm - 3mm For non-uniform overlays, the maximum curve in the overlay is limited to a 1mm height difference over the trackpad surface as shown in Figure 1.3. Maximum Height variation of 1mm Overlay Adhesive PCB PCB Figure 1.3 Maximum height variation in the overlay. 1.7 Output Level The output level of the output pins can be changed from active high (default) to active low. This change is accomplished by connecting solder link S2 on the module during module integration into the application. The same output level is applicable on all 5 output pins. 1 Note: Pilot Built 1 (PB1) modules only support the 1-2mm setting. Contact Azoteq for updated FW. Copyright (c) Azoteq (Pty) Ltd 2015.

Solder link S2 Output Level Open Closed Active High Active Low 1.8 Finger Sizes Because the modules are different physical sizes, but keep the same resolution, the trackpad pitch is different between the modules. Therefore a small variation in minimum finger size is expected. The smallest and largest finger sizes allowed for valid gestures on each module are shown in Table 1.5 below.

Trackpad Module Datasheet V1.03 Page 12 of 20 September 2015 IQ Switch(R) ProxSense(R) Series 8 Gesture Implementation 8.1 Swipe Gestures There are four swipe gestures that can be detected by the trackpad modules, as shown in Figure 8.1 below. Figure 8.1 Illustrations off the 4 swipe gestures that can be detected by the trackpad modules. Each time any of the swipe gestures are performed correctly (correct finger action within a 18ms to 1 second window), the corresponding I/O pin of the trackpad will output a single 200ms pulse to the Bluetooth IC. The user has the option to select a high (default) or low (by adding a solder link on the module) pulse. The high level as indicated on the figure below will correspond to the input voltage supplied to the trackpad module. VDDHI VDDHI 200ms 200ms 0V 0V I/O Output - High Pulse I/O Output - Low Pulse Figure 8.2 High output pulse shown on the left; Low output pulse shown on the right. 8.1.1 Swipe Upward (A) A single finger action as shown in Figure 8.1 part A, place anywhere on the trackpad surface, and moved more than 14mm from the bottom to the top within 1s and then lifted off the trackpad will generate a 200ms pulse on I/O_1. The swipe gesture is limited to finger movement < +-45 degrees from the vertical, and dependent on the finger not lifting off the trackpad during the finger movement stage. 8.1.2 Swipe Downward (B) A single finger action as shown in Figure 8.1 part B, place anywhere on the trackpad surface, and moved more than 14mm from the top to the bottom within 1s and then lifted off the trackpad will generate a 200ms pulse on I/O_3. The swipe gesture is limited to finger Copyright (c) Azoteq (Pty) Ltd 2015. All rights reserved. Trackpad Module Datasheet V1.03 Page 13 of 20 September 2015 IQ Switch(R) ProxSense(R) Series movement < +-45 degrees from the vertical, and dependent on the finger not lifting off the trackpad during the finger movement stage. 8.1.3 Swipe Backward (C) A single finger action as shown in Figure 8.1 part C, place anywhere on the trackpad surface, and moved more than 14mm from right to left within 1s and then lifted off the trackpad will generate a 200ms pulse on I/O_4. The swipe gesture is limited to finger movement < +-45 degrees from the horizontal, and dependent on the finger not lifting off the trackpad during the finger movement stage. 8.1.4 Swipe Forward (D) A single finger action as shown in Figure 8.1 part D, placed anywhere on the trackpad surface, and moved more than 14mm from left to right within 1s and then lifted off the trackpad will generate a 200ms pulse on I/O_5. The swipe gesture is limited to finger movement < +-45 degrees from the horizontal, and dependent on the finger not lifting off the trackpad during the finger movement stage. 8.2 Tap Gesture The trackpad modules can recognize a tap gesture, from a single finger, at any point on the trackpad surface. A valid tap gesture is recognized if a touch is made by moving less than 4mm on the overlay surface and release within 600ms but not faster than 18ms. When a valid tap is detected, the modules will output a 200ms pulse on I/O_2 as shown in Figure 8.2. Figure 8.3 Tap Gesture. 8.3 Tap and Hold Gesture The trackpad modules can recognize a tap & hold gesture, from a single finger, at any point on the trackpad surface. A valid tap & hold gesture is recognized if a touch is made and the finger does not release the touch for more than 600ms without moving more than 4mm on the trackpad overlay surface. Figure 8.4 Tap& Hold Gesture. When a valid tap & hold is detected, the modules will output a continuous pulse (continuous high level of the output, or low if solder link is made) on I/O_2 until the finger is lifted off the trackpad.

Figure 8.6 Illustrations off the 4 swipe & hold gestures that can be detected by the trackpad modules. Each time any of the swipe & hold gestures are performed correctly, the corresponding I/O pin of the trackpad will continuously output 200ms pulses to the Bluetooth IC. The user has the option to select a high (default) or low (by adding a solder link on the module) pulse. The high level as indicated on the figure below will correspond to the input voltage supplied to the trackpad module. 8.4.2 Swipe Upward & Hold (A) A single finger action as shown in Figure 8.6 part A, placed anywhere on the trackpad surface, and moved more than 14mm from the bottom to the top within 1s and then kept stationary on the trackpad for 600ms or more will generate continuous 200ms pulses on I/O_1. The swipe gesture is limited to < +-45 degrees from the vertical, and dependent on the finger not lifting off the trackpad during the finger movement stage. The output pulses will stop once the finger is lifted off the trackpad. Copyright (c) Azoteq (Pty) Ltd 2015. All rights reserved.

The swipe gesture is limited to < +-45 degrees from the vertical, and dependent on the finger not lifting off the trackpad during the finger movement stage. The output pulses will stop once the finger is lifted off the trackpad. 8.4.4 Swipe Backward & Hold (C) A single finger action as shown in Figure 8.6 part C, placed anywhere on the trackpad surface, and moved more than 14mm from right to left within and then kept stationary on the trackpad for 600ms or more will generate continuous 200ms pulses on I/O_4. The swipe gesture is limited to < +-45 degrees from the vertical, and dependent on the finger not lifting off the trackpad during the finger movement stage. The output pulses will stop once the finger is lifted off the trackpad. 8.4.5 Swipe Forward & Hold (D) A single finger action as shown in Figure 8.6 part D, place anywhere on the trackpad surface, and moved more than 14mm from left to right within 1s and then kept stationary on the trackpad for 600ms or more will generate continuous 200ms pulses on I/O_5.
