DS2482-100 I2C to 1-Wire Master Breakout

Seamless I2C to 1-Wire Integration for Embedded Applications: Boost Compatibility and Communication Efficiency

The 7Semi DS2482-100 I2C to 1-Wire Master Breakout is a high-performance hardware interface designed to simplify protocol bridging between I2C and 1-Wire networks in embedded systems. Powered by the DS2482-100 IC, this module delivers precise and efficient communication for sensor-driven designs, data logging setups, and intelligent peripheral control, eliminating the complexity of host-side waveform generation. Operating across standard (100kHz) and fast (400kHz) I2C speeds, the breakout facilitates robust two-way data exchange with 1-Wire slave devices such as temperature sensors, memory chips, and digital switches.

Engineered for flexibility and reliability, the breakout module supports both standard and Overdrive 1-Wire speeds, ensuring compatibility with a broad range of devices. It features onboard timing control, configurable I2C slave address pins, and intelligent signal processing, making it an ideal tool for developers and engineers working in industrial automation, environmental monitoring, or IoT projects. Integrated programmable strong pullup control and external MOSFET support provide additional current sourcing for energy-demanding 1-Wire devices, enhancing overall performance in complex embedded environments.
