I am programming a pi pico-w with a BME280 with Thonny  
I found an example for it . On top of the program there was a line “import bme280”  
Thonny said: no module named ‘bme280’  
I did a search in Thonny Tools \> Manage Packages. No result.  
To check the Search function I searched on SSD1306. That worked ok.  
Why was the bme280 or BME280 not found?

On Github I saw several drivers for bme280.py.  
How can I upload this driver into the flash memory of the pi pico-w?

If you use Pimoroni’s custom uf2 it should be good to go.

Thank you for your reply.  
Sometimes I wrote on a random website that you have to copy the bme280.py to the subdirectory /lib. And after searching /lib I found that one can type in the Shell :

> > > import sys  
> > > sys.path  
> > > [‘’, ‘/lib’, ‘/mylib’]

Because I don’t have much experience with micropython yet, it didn’t immediately dawn on me that the location of /lib is on the Pi Pico. So I did initially a search of /lib on my pc.  
Now my program is working, after copying bme280.py to /lib of the Pi Pico.
