It is powered by the TM6605 driver chip and supports LRA resonant frequencies from 140Hz to 220Hz.The module includes 44 built-in vibration modes, so you can quickly add effects such as subtle clicks, alerts and stronger rumble-style feedback without manually programming waveforms. Automatic resonance tracking helps the driver lock onto the actuator’s optimal frequency for consistent vibration strength.Connection is through the Gravity I2C interface, making it easy to use with boards such as Arduino, Raspberry Pi and UNIHIKER. The package includes the haptic motor driver, a Gravity 4pin sensor cable and an LRA motor for rapid prototyping.Features:Rich haptic library with 44 built-in modes: Provides pre-programmed vibration patterns for quick tactile effects.Automatic resonance tracking: Detects and locks onto the LRA’s optimal frequency for stronger, crisper feedback.Plug-and-play Gravity I2C integration: Uses the standard Gravity I2C interface for simple microcontroller connection.Simple I2C commands: Translates commands into precise, high-fidelity tactile sensations.Wide project compatibility: Suitable for Arduino, Raspberry Pi and UNIHIKER based builds.Complete package: Includes Gravity: Haptic Motor Driver x1, Gravity 4pin sensor cable x1 and LRA motor x1.Specifications:Operating Voltage: 3.7V ~ 5.2V DCInterface: Gravity I2CDriver Chip: TM6605Supported LRA Frequency: 140Hz ~ 220HzBuilt-in Effects: 44 Vibration ModesStandby Current: 9.5μAOperating Temperature: -40°C ~ +85°CPCB Dimensions: 30mm * 20mmMounting Hole Size: φ3.0mIdeal for immersive game controllers, interactive robotics, responsive UI/UX panels, VR/AR haptics and silent notification systems. ## Images - [Image 1](https://littlebirdelectronics.com.au/rails/active_storage/blobs/redirect/BAh7BkkiC19yYWlscwY6BkVUewdJIglkYXRhBjsAVGkDTUsBSSIIcHVyBjsAVEkiDGJsb2JfaWQGOwBG--b56771e276bb7c91ef97db80a2763a92362acc03/DRI0056_Main_01-1.jpg) - [Image 2](https://littlebirdelectronics.com.au/rails/active_storage/blobs/redirect/BAh7BkkiC19yYWlscwY6BkVUewdJIglkYXRhBjsAVGkDVUsBSSIIcHVyBjsAVEkiDGJsb2JfaWQGOwBG--00e15d05218c0bea2d71cdd8595be3b9f15f74fc/DRI0056_Main_01.jpg) - [Image 3](https://littlebirdelectronics.com.au/rails/active_storage/blobs/redirect/BAh7BkkiC19yYWlscwY6BkVUewdJIglkYXRhBjsAVGkDX0sBSSIIcHVyBjsAVEkiDGJsb2JfaWQGOwBG--dc1ac00e333a545915aeed3d6952438437724220/DRI0056_Dim_02.jpg) - [Image 4](https://littlebirdelectronics.com.au/rails/active_storage/blobs/redirect/BAh7BkkiC19yYWlscwY6BkVUewdJIglkYXRhBjsAVGkDZksBSSIIcHVyBjsAVEkiDGJsb2JfaWQGOwBG--9282fb3b3222e1dbcc87c663faf547bb3c2ed77a/DRI0056_Back_03.jpg) - [Image 5](https://littlebirdelectronics.com.au/rails/active_storage/blobs/redirect/BAh7BkkiC19yYWlscwY6BkVUewdJIglkYXRhBjsAVGkDb0sBSSIIcHVyBjsAVEkiDGJsb2JfaWQGOwBG--9f2cdb235f6acb7daae466a29b966a26d677af01/DRI0056_Detail_05.jpg) - [Image 6](https://littlebirdelectronics.com.au/rails/active_storage/blobs/redirect/BAh7BkkiC19yYWlscwY6BkVUewdJIglkYXRhBjsAVGkDc0sBSSIIcHVyBjsAVEkiDGJsb2JfaWQGOwBG--c2655d25b17a0763413781f194a6910915c2ba37/DRI0056_Detail_04.jpg) --- ## Finding & Searching Products If a part listed here isn't quite what you need, you can search Little Bird Electronics' full catalogue: - **Search by keyword:** `GET https://littlebirdelectronics.com.au/products.md?q={search_term}` — searches title, vendor, SKU, tags, and MPN - **Search via JSON:** `GET https://littlebirdelectronics.com.au/products.json?q={search_term}` — structured JSON results - **Browse by collection:** `GET https://littlebirdelectronics.com.au/collections/{handle}.json` — products in a specific collection - **Filter in-stock only:** `GET https://littlebirdelectronics.com.au/products.md?q={term}&in_stock=1` - **Individual product detail:** `GET https://littlebirdelectronics.com.au/products/{handle}.md` — full specs, pricing, stock levels, variants Search supports multi-word queries (AND logic).
