The PiWire+ is a 1-Wire host adapter for use with Raspberry Pi model A+ and B+, Raspberry Pi 2 model B, and Raspberry Pi 3 model B. The PiWire+ features seventeen 1-Wire channels allocated to three independent 1-wire controllers.

Please read the documentation before you begin using your PiWire+. The user manual contains important information about setting up the PiWire+.

The 1-Wire Automation Software fully supports the PiWire+.

The PiWire+ can be used with the owfs software.



The PiWire+ offers basic ESD protection. While suited for everyday indoor applications, this ESD protection is not capable of protecting the 1-Wire host adapters and the Raspberry Pi against the effects of nearby lightning strikes, especially when using 1-Wire devices and cabling outdoors (for example weather stations). When connecting outdoor equipment and cabling, additional ESD protection circuits are necessary. More information about this can be found in the manual.


PiWire+ is the new name given to the AbioWire+ product
