I am trying to build this, but I run into a conflict (I assume) :
D1/D2 on Wemos D1 Mini are SDA/SCL lines for the I2C bus.
According to the schematics, the SDS011 is also connected by default to D1/D2 on a Wemos running a serial Protocol.

SDS is running on 5V, BME280 is running at 3.3V, on the same pins ?

How can this work ?
