This board features the IQS7211A, a tiny capacitive touch controller from Azoteq. A low-power dedicated wake-up touch controller launches a complete touchscreen sensing solution with a 25.4 x 29mm trackpad dimension, best-in-class sensitivity, and power consumption. It is characterized by embedded gesture engine recognition for simple gestures (tap, swipes, hold) and built-in noise detection and filtering. This Click boardâ�¢ is suitable for human-machine interfaces, keypad or scrolling functions, single-finger gesture-based interfaces, and more.\u003c\/p\u003e \u003cp\u003eTouchpad 4 Click is supported by a mikroSDK compliant library, which includes functions that simplify software development.\u003c\/p\u003e \u003cp\u003eTouchpad 4 Click as its foundation uses the IQS7211A, a tiny trackpad controller designed for multitouch applications using a projected capacitance touch panel from Azoteq. The IQS7211A is part of Azoteqâ��s latest range of ProxFusion combination sensors, a multi-sensor technology that offers combinations of capacitive sensing, Hall-effect, inductive, and temperature sensing on a single integrated circuit. It allows users to control a trackpad of up to 32-channels and offers high resolution and fast response, low power consumption, and long-term activation supported by environmental tracking. It is also characterized by embedded gesture engine recognition for simple gestures (tap, swipes, hold) and built-in noise detection and filtering.\u003c\/p\u003e \u003cp\u003eOn the Touchpad 4 Click front side, there is a clearly defined field that represents a touchpad area. This area is a matrix of conductive electrodes on the PCB, electrically isolated from each other, arranged as rows and columns of X and Y. An electrode consists of multiple diamond-shaped elements, each connected to the next with a conductive neck.\u003c\/p\u003e \u003cp\u003eThe controller uses the principle of projected capacitance charge transfer on the touchpad area. When a conductive object such as a human finger approaches the sense plate, it will decrease the detected capacitance. Observing the measured results at various sensing points on the touchpad area enables the controller to determine proximity\/hover detection and contact (touch) detection on all channels and accurately determine the coordinates on the touch area.\u003c\/p\u003e \u003cp\u003eTouchpad 4 Click communicates with MCU using a standard I2C 2-Wire interface, with a clock frequency up to 1MHz in the Fast Mode. An additional ready signal, routed on the INT pin of the mikroBUSâ�¢ socket, is added, which indicates when the communication window is available. Thus, it is optimal for the response rate to use the INT pin as a communication trigger. Alongside this pin, this Click boardâ�¢ has a Reset feature routed to the RST pin on the mikroBUSâ�¢ socket, which with a low logic level puts the module into a Reset state, and with a high level operates module normally.\u003c\/p\u003e \u003cp\u003eThis Click boardâ�¢ can be operated only with a 3.3V logic voltage level. The board must perform appropriate logic voltage level conversion before use with MCUs with different logic levels. However, the Click boardâ�¢ comes equipped with a library containing functions and an example code that can be used, as a reference, for further development.\u003c\/p\u003e \u003cp\u003e\u003cstrong\u003eFeatures:\u003c\/strong\u003e\u003c\/p\u003e \u003cul\u003e \u003cli\u003eInterface: I\u003csup\u003e2\u003c\/sup\u003eC\u003c\/li\u003e \u003cli\u003eCompatibility: mikroBUSâ�¢\u003c\/li\u003e \u003cli\u003eDimensions: 57.15 x 25.4mm\u003c\/li\u003e \u003cli\u003eInput Voltage: 3.3V\u003c\/li\u003e \u003cli\u003eActive Mode Current Consumption: 1.4mA\u003c\/li\u003e \u003cli\u003eOperating Temperature Range: Min. -40�°C, Typ. +25�°C, Max. +85�°C\u003c\/li\u003e \u003c\/ul\u003e \u003cp\u003e\u003cstrong\u003eDocuments:\u003c\/strong\u003e\u003c\/p\u003e \u003cul\u003e \u003cli\u003e\u003ca href=\"https:\/\/cdn.sparkfun.com\/assets\/f\/0\/1\/b\/3\/Schematic-19188-Touchpad_4_Click.PDF\"\u003eSchematic\u003c\/a\u003e\u003c\/li\u003e \u003cli\u003e\u003ca href=\"https:\/\/cdn.sparkfun.com\/assets\/5\/3\/f\/a\/b\/IQS7211A_Datasheet.pdf\"\u003eIQS7211A Datasheet\u003c\/a\u003e\u003c\/li\u003e \u003cli\u003e\u003ca href=\"https:\/\/www.mikroe.com\/mikrosdk\"\u003emikroSDK\u003c\/a\u003e\u003c\/li\u003e \u003cli\u003e\u003ca href=\"https:\/\/github.com\/MikroElektronika\/mikrosdk_click_v2\/tree\/master\/clicks\/touchpad4\"\u003eGitHub\u003c\/a\u003e\u003c\/li\u003e \u003c\/ul\u003e \u003cp\u003e\u003cstrong\u003eVideos\u003c\/strong\u003e\u003c\/p\u003e \u003cdiv class=\"flex-video-wrap clearfix\"\u003e \u003cdiv class=\"flex-video widescreen img\"\u003e \u003ciframe src=\"https:\/\/www.youtube.com\/embed\/zzlh1oGii1Q\/?autohide=1\u0026amp;border=0\u0026amp;wmode=opaque\u0026amp;enablejsapi=1\" frameborder=\"0\" allowfullscreen width=\"560\" height=\"315\"\u003e\u003c\/iframe\u003e \u003c\/div\u003e \u003c\/div\u003e","brand":"sparkfun-10","offers":[{"title":"Default Title","offer_id":40054696181845,"sku":"19188:SEN-19188:spark","price":1855.0,"currency_code":"INR","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1034\/1611\/products\/19188_-_Touchpad_4_Click_2.jpg?v=1651343370","url":"https:\/\/www.tanotis.com\/products\/sparkfun-mikroe-touchpad-4-click","provider":"Tanotis","version":"1.0","type":"link"}
