    Thanks for sharing the schematic and layout — this gives a much clearer picture. A few specific observations now that I can see the full design. DS18B20 dual pull-up situation From your schematic I can see R6 on U5 and R7 on U4, both connecting to the OW_DQ net. If both sensors share the same...
