Circuit Analysis

Before you layout a circuit, it's generally a good idea to understand what is happening in your schematic.  And before you lay out a schematic, it's generally a good idea to understand what is happening in your block diagram.

BME280 Circuit

Of all the integrated circuits on the board, this is perhaps the easiest one to implement.  Simply place one decoupling capacitor at Vdd (pin8) and one decoupling capacitor at VDDIO (pin6).  Communication is via I²C, and should be relatively easy to implement.
