5V 1-wire Bus

Post by mob » Thu Oct 27, 2016 12:28 pm


I need to run the 1-wire bus on 5V because of long distances to the sensors. Therefore I want to do a setup as shown here: http://www.fhemwiki.de/wiki/Datei:Levelshifter.png.
To do so I need to remove the 1-wire (GPIO4) 3v3 pull-up resistor on the UPS Pico - where can I find it? Or do you have an other suggestion to get a 5V 1-wire bus?
