{"product_id":"sparkfun-mikroe-haptic-3-click","title":"SparkFun MIKROE Haptic 3 Click","description":"\u003cp\u003eHaptic 3 Click is a compact add-on board that uses advanced vibration patterns and waveforms to convey information to a user. This board features the DA7282, a linear resonant actuator (LRA), and an eccentric rotating mass (ERM) haptic driver from Dialog Semiconductor. The DA7282 features LRA or ERM drive capability with automatic closed-loop LRA resonant frequency tracking, guaranteeing consistency across LRA production tolerances. It also offers wideband operation that fully utilizes the capabilities of newer wideband and multi-directional LRAs, alongside three external general-purpose inputs for triggering up to six independent haptic sequences. This Click boardâ�¢ is suitable for numerous everyday applications such as indicator systems, training equipment\/simulators with haptics function, robotics and mechatronics, and more.\u003c\/p\u003e \u003cp\u003eHaptic 3 Click is supported by a mikroSDK compliant library, which includes functions that simplify software development.\u003c\/p\u003e \u003cp\u003eHaptic 3 Click as its foundation uses the DA7282, a haptic driver capable of driving both LRA and ERM actuators from Dialog Semiconductor. The power-optimized architecture and advanced closed-loop digital algorithms achieve a high-fidelity haptic drive. The DA7282 features frequency control within an onboard Waveform Memory and three distinct general-purpose inputs for triggering up to six specific sequences, which helps with emulating button pressing in many applications.\u003c\/p\u003e \u003cp\u003eThe device controls drive levels based on the sequence selected by the I2C interface across the load and senses the movement of the actuator. The driven waveform is generated by a current regulated loop using a high-frequency PWM modulation. The differential output drive features a switching regulator architecture with an H-bridge differential drive across the load at 187.5kHz. The DA7282 is also capable of closed-loop actuator monitoring while driving to enable calibration-free playback, frequency tracking (LRA only), Active Acceleration, Rapid Stop, and actuator diagnostics.\u003c\/p\u003e \u003cp\u003eResonant frequency tracking can be enabled while driving an LRA to track the mechanical resonance of the actuator through closed-loop control or can be disabled to operate DA7282 in open-loop wideband frequency operation while driving LRAs with a broader bandwidth frequency response. Also, Active Acceleration and Rapid Stop features enable automated driving of both ERM and LRA loads (when frequency tracking is enabled), which reduces the time to reach the target acceleration level and the time for the actuator to come to a complete stop.\u003c\/p\u003e \u003cp\u003eAlthough it can use both mikroBUSâ�¢ power rails for regular power supply, its digital part requires a voltage level of 1.8V to work correctly. Therefore, a small regulating LDO is used, the BH18PB1WHFV, providing a 1.8V out of both 5V and 3.3V mikroBUSâ�¢ power rails, alongside Enable feature through the EN pin routed to the CS pin of the mikroBUSâ�¢ socket offering a switch operation to turn ON\/OFF power delivery to the connected load.\u003c\/p\u003e \u003cp\u003eHaptic 3 Click communicates with MCU using the standard I2C 2-Wire interface with a maximum clock frequency of 400kHz. Since the sensor for communication requires a logic level of 1.8V, this Click boardâ�¢ also features the PCA9306 voltage-level translator. The I2C interface bus lines are routed to the voltage-level translators allowing this Click boardâ�¢ to work with both 3.3V and 5V MCUs properly. Also, it uses an interrupt pin, marked as IRQ and routed to the INT pin of the mikroBUSâ�¢ socket, used for when a different fault condition occurs to alert the MCU.\u003c\/p\u003e \u003cp\u003eThis Click boardâ�¢ can operate with both 3.3V and 5V logic voltage levels selected via the VCC SEL jumper. This way, it is allowed for both 3.3V and 5V capable MCUs to use the communication lines properly. However, the Click boardâ�¢ comes equipped with a library that contains easy-to-use 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: 42.9 x 25.4mm\u003c\/li\u003e \u003cli\u003eInput Voltage: 3.3V or 5V\u003c\/li\u003e \u003cli\u003eSupply Voltage: Min. 3.3, Max. 5V\u003c\/li\u003e \u003cli\u003eMaximum Output Current: Typ. 250mA, Max. 500mA\u003c\/li\u003e \u003cli\u003eLRA Wideband Frequency Range: Min. 25Hz, Max. 1000Hz\u003c\/li\u003e \u003cli\u003eLRA Frequency Tracking Range: Min. 50Hz, Max. 300Hz\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\/5\/7\/4\/d\/1\/Schematic-19645-MIKROE_Haptic_3_Click.PDF\"\u003eSchematic\u003c\/a\u003e\u003c\/li\u003e \u003cli\u003e\u003ca href=\"https:\/\/cdn.sparkfun.com\/assets\/6\/9\/7\/e\/6\/BH18PB1WHFV_datasheet.pdf\"\u003eBH18PB1WHFV Datasheet\u003c\/a\u003e\u003c\/li\u003e \u003cli\u003e\u003ca href=\"https:\/\/cdn.sparkfun.com\/assets\/6\/7\/a\/d\/e\/DA7282_datasheet.pdf\"\u003eDA7282 Datasheet\u003c\/a\u003e\u003c\/li\u003e \u003cli\u003e\u003ca href=\"https:\/\/cdn.sparkfun.com\/assets\/9\/a\/5\/b\/9\/PCA9306_datasheet.pdf\"\u003ePCA9306 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:\/\/libstock.mikroe.com\/projects\/view\/4903\/haptic-3-click\"\u003eLibStock\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":40054691463253,"sku":"19645:ROB-19645:spark","price":2530.0,"currency_code":"INR","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1034\/1611\/products\/19645_-_MIKROE_Haptic_3_Click_2.jpg?v=1651342747","url":"https:\/\/www.tanotis.com\/products\/sparkfun-mikroe-haptic-3-click","provider":"Tanotis","version":"1.0","type":"link"}
