It allows any I2C-capable microcontroller or single-board computer to communicate with 1-Wire devices — most commonly DS18B20 temperature sensors — without needing to bit-bang the 1-Wire protocol.\n\nThe eight selectable channels let you assign each sensor to a dedicated channel, eliminating the need to identify sensors by their unique ROM addresses. This makes sensor swaps and installations straightforward. The breakout supports both parasitic and external power modes, operates at 3.3V or 5V, and features an adjustable I2C address for multi-device buses.\n\nKey Features\n\n\n8 Selectable 1-Wire Channels – Know exactly which sensor is on which channel\n\nI2C to 1-Wire Bridge – No bit-banging required; works with any I2C host\n\nParasitic Power Support – Built-in pull-ups for parasitic-powered 1-Wire devices\n\nAdjustable I2C Address – Multiple adapters on the same I2C bus\n\n3.3V and 5V Compatible – STEMMA QT voltage also powers 1-Wire peripherals\n\nSTEMMA QT / Qwiic Connectors – Solderless I2C connection and daisy-chaining\n\n\nIdeal For\n\nMulti-sensor DS18B20 temperature monitoring\nAdding 1-Wire support to microcontrollers without native protocol support\nDesktop or SBC data acquisition via I2C\nEnvironmental monitoring with identified sensor locations\n\n\nPackage Contents\n\n1× DS2482S-800 I2C-to-1-Wire adapter breakout with STEMMA QT connectors\n\n\n\nNote: STEMMA QT cable and 1-Wire sensors not included.\n","vendor":"Adafruit","product_type":"physical","in_stock":false,"options":[],"variants":[{"id":809,"title":"Default Title","sku":"AF-6027","mpn":"ADA6027","price":39.44,"compare_at_price":0.0,"on_sale":false,"in_stock":false,"available_quantity":0,"option1":"Default Title"}]}
