1-Wire to Qwiic Bridge - DS28E17
Discontinued
The 1-Wire to Qwiic Bridge lets you communicate via I2C over very long distances — up to approximately 100 metres depending on the application. It works by packetising I2C data as 1-Wire packets, sending them over the 1-Wire bus to the DS28E17 bridge chip, which translates them back to I2C for any connected slave device. Communication is bidirectional.
Multiple bridges can be daisy-chained for multi-node networks, with footprints for both RJ45 and RJ11 connectors provided for convenient wiring. Each DS28E17 has a unique 64-bit ROM address, allowing I2C devices with limited addressing to be attached to separate bridges and addressed individually — no multiplexer needed.
Key Features
