1-Wire to Qwiic Bridge - DS28E17

Stock code: SPX-14291

The 1Wire-to-Qwiic Bridge allows you to communicate via I2C over very long distances. It does so by utilizing the 1Wire communication protocol, which can communicate at distances of up to about 100 meters, depending on the application. The I2C information is packetized as a 1Wire packet, sent over the 1Wire bus to the DS28E17 Bridge, and translated to I2C for any slave device connected to the Bridge. Communication happens bi-directionally. Please note that the DS28E17 is a 1Wire IN/ I2C OUT device, meaning the master device needs to be connected to a 1Wire bus to communcate with the bridge.

Multiple 1Wire-to-Qwiic Bridges can be daisy-chained for multi-node networks. Footprints for both an RJ45 connector as well as an RJ11 connector have been added for convenient networking.

Each DS28E17 comes programmed with a unique 64-bit ROM registration number that serves as a node address in the 1-Wire network. This means that I2C devices that have limited or only a sinlge I2C address can be attached to separate 1Wire-to-Qwiic Bridges and addressed individually without the need of a multiplexer or other complicated addressing scheme.

The Qwiic system enables fast and solderless connection between popular platforms and various sensors and actuators. You can read more about the Qwiic system here. We carry 200mm, 100mm, 50mm, and breadboard friendly Qwiic cables.
