Description
The Adafruit DS2482S-800 is a versatile STEMMA QT board featuring an I2C-to-1-Wire controller chip with 8 selectable channels. Designed with built-in parasitic-power pullups, an adjustable I2C address, and a wide operating voltage range, this adapter makes it easy to connect multiple 1-Wire devices like DS18B20 temperature sensors to your I2C bus.
The 1-Wire protocol allows multiple devices to share a single data wire plus ground, ideal for sensor networks. The 8 channel selection helps identify individual sensors without needing to read unique identifiers, simplifying sensor management and replacement.
Key features include the compact STEMMA QT form factor with compatible connectors for solderless, chainable connections, supporting both 3V and 5V power through the cable. This adapter is perfect for expanding the number of 1-Wire sensors on microcontrollers or single-board computers that may lack native 1-Wire support.
