Simply connect it to an existing I2C bus and use the screw terminals to attach DS18B20 temperature sensors or other 1-Wire devices. The 1-Wire protocol, originally developed by Dallas Semiconductor, uses a single data wire plus ground (and an optional power wire) to communicate with multiple sensors or memory chips on a shared bus. While you can bit-bang 1-Wire on most microcontrollers, the DS2484 provides a dedicated hardware bridge for platforms without native 1-Wire support — including desktop computers and single-board computers with I2C. Key Features DS2484 Controller – Single-channel I2C-to-1-Wire bridge with hardware protocol handling ESD Protection – Built-in electrostatic discharge protection for the 1-Wire bus Split Supply Support – Independent voltage for the 1-Wire power pin via cuttable trace and terminal block injection Screw Terminals – Easy connection for 1-Wire devices without soldering STEMMA QT / Qwiic – Dual I2C connectors for solderless daisy-chaining with other I2C devices Wide Voltage Range – Works with 3.3V or 5V logic from the STEMMA QT cable Also Available DS2482S-800 – 8-Channel I2C to 1-Wire Bus Adapter Ideal For DS18B20 temperature sensor networks Adding 1-Wire capability to I2C-only platforms Long-distance sensor wiring with shared bus topology Prototyping with breadboard-friendly breakout form factor Package Contents 1× Adafruit DS2484 I2C to 1-Wire Bus Adapter Breakout (fully assembled) **Product Type:** physical ## Images - [Image 1](https://littlebirdelectronics.com.au/rails/active_storage/blobs/redirect/BAh7BkkiC19yYWlscwY6BkVUewdJIglkYXRhBjsAVGkCghFJIghwdXIGOwBUSSIMYmxvYl9pZAY7AEY=--9f6ca740eca77bcb35f8ebc1db4d0603ea617daf/image_3f88be4d-8851-4888-aabb-1178cf9f5fae.jpg) - [Image 2](https://littlebirdelectronics.com.au/rails/active_storage/blobs/redirect/BAh7BkkiC19yYWlscwY6BkVUewdJIglkYXRhBjsAVGkCgxFJIghwdXIGOwBUSSIMYmxvYl9pZAY7AEY=--eaa329d54f0e8bd3d7af8bdebba8bed0461ae683/image_6006ac3a-0e67-416e-8961-cd38ee3a9efd.jpg) - [Image 3](https://littlebirdelectronics.com.au/rails/active_storage/blobs/redirect/BAh7BkkiC19yYWlscwY6BkVUewdJIglkYXRhBjsAVGkChBFJIghwdXIGOwBUSSIMYmxvYl9pZAY7AEY=--8189f1cad838aada998d18dabc2d8a6fc6458bd7/image_5a87a615-151a-460c-8a92-9c3eb2dc7c8d.jpg) - [Image 4](https://littlebirdelectronics.com.au/rails/active_storage/blobs/redirect/BAh7BkkiC19yYWlscwY6BkVUewdJIglkYXRhBjsAVGkChRFJIghwdXIGOwBUSSIMYmxvYl9pZAY7AEY=--7c50d9fec5cc1fd1c85b758c57fb9b0300c3c25c/image_acd6870d-f716-449e-8348-6bac4e120edc.jpg) - [Image 5](https://littlebirdelectronics.com.au/rails/active_storage/blobs/redirect/BAh7BkkiC19yYWlscwY6BkVUewdJIglkYXRhBjsAVGkChhFJIghwdXIGOwBUSSIMYmxvYl9pZAY7AEY=--1b31e29828f23a75cdb8bb5677d2f8ddb47d3525/image_a0dc890b-1193-402f-b3f5-a7d1c698c0d5.jpg) - [Image 6](https://littlebirdelectronics.com.au/rails/active_storage/blobs/redirect/BAh7BkkiC19yYWlscwY6BkVUewdJIglkYXRhBjsAVGkChxFJIghwdXIGOwBUSSIMYmxvYl9pZAY7AEY=--d296b02811abb388c6a8d7ea2157e0e7d41a22d5/image_44103c62-f222-4c16-9eec-de6b64a36b27.jpg) - [Image 7](https://littlebirdelectronics.com.au/rails/active_storage/blobs/redirect/BAh7BkkiC19yYWlscwY6BkVUewdJIglkYXRhBjsAVGkCiBFJIghwdXIGOwBUSSIMYmxvYl9pZAY7AEY=--5ca77b72d142ff2fb67660ffc5a4dccb2b9e23bb/image_da1f345e-f0fe-416a-9186-7c5bb8707eb6.jpg) - [Image 8](https://littlebirdelectronics.com.au/rails/active_storage/blobs/redirect/BAh7BkkiC19yYWlscwY6BkVUewdJIglkYXRhBjsAVGkCiRFJIghwdXIGOwBUSSIMYmxvYl9pZAY7AEY=--ceffdc6dd98689ceb044db22a49dd6e882046cc5/image_da6d5a8d-bb4f-434b-b9c9-4ec1a7569e18.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).
