Adafruit DS2484 I2C to 1-Wire Bus Adapter Breakout

This DS2484 Stemma QT board is an efficient I2C-to-1-Wire controller chip. With integrated ESD protection and support for split supplies, it connects seamlessly to existing I2C buses. Use the screw terminals to attach multiple DS18B20 sensors or pair with 1-Wire chaining breakouts for more advanced experiments.

This board uses the 1-Wire protocol, ideal for long-distance wiring and simple sensor chaining on a shared bus wire. Designed in the compact STEMMA QT form factor, it ensures easy interfacing and is compatible with SparkFun Qwiic connectors. This enables solderless connections between development boards and the DS2484, as well as chaining with various sensors and accessories.

For versatile power options, the board can be powered via the STEMMA QT cable using 3V or 5V. To customize the voltage on the 1-Wire power pin, simply cut the onboard trace and apply your desired voltage to the terminal block. Enhance your projects with reliable 1-Wire device support, even on setups lacking built-in functionality.
