====== 1-Wire ====== 
1-Wire (abbreviated to 1W or OW), is a communication bus system designed for low-speed data transmission, signalling and power through a single wire. 

<WRAP center round box>
To improve reliability, Unipi 1-Wire devices are designed for the best possible seriality and stability. This is achieved by using four conductors (GND, VCC, DATA-IN, DATA-OUT) - this arrangement is used for 8-port hubs, 1-Wire temperature sensors and [[https://www.unipi.technology/cs/1-wire-c3|other products from the Unipi 1W product range]]
