I swapped the Adafruit KB2040 over for a Marble Pico I had around, it is a super charged Pico with a stemmaQT port 8mb of external flash onboard, and a handy SD card slot. Then became a big issue of aligning the right I2C ports. I jumped back and forth between micropython and cicuitpython as well and settled on circuitpython as it is more supported lib wise it seems... I have yet to get logging going but I did add a startup timer/countdown for the sensor and then a "static" display on the serial output. It works sort of, and really is a bad method of doing it, seems circuitpython does not really have the same functions for clearing the serial output. 

I ended up with this "AI FIELD ANALYZER v1.0 | Time: 10:08:57 | CO₂: 408 ppm | TVOC: 0 ppb | ✅ Excellent air quality, no ventilation needed. | ✅ No significant VOCs detected—air is clean...ly."

Unsure on the 64gig SD card may just be too much for it, plus I need a fat32 format as well. 

Code is getting a bit long so, this is likely the last time I post it here and will be making a Github for it.
