There is a voltage drop of 0.2v across the data and clock pin of the BME280 in our design and we took the reference from datasheet. In our schematic VDD pin and vDDIO pin uses same DC power supply. But in datasheet it is mentioned that vDD pin is analog and vDDIO is for digital interface. So, want know whether the design is good or need some suggestions from your team. Or, is it ok to leave the vDD pin floating and use vDDIO for interafce as well as supply.
And i've added the schematics image for your reference. I'm looking forward on your reply ASAP!
Both VDD and VDDIO must be supplied for the sensor to operate, but it is fine to have them supplied from the same source. Based on your system/requirements you may want to double-check your pull-up resistors values (based on interface timing and bus load) , but your schematic looks correct and follows our recommendations.
