2PCS SGP30 Air Measurement Gas Sensor TVOC/eCO2 Air Quality Carbon Dioxide Detector to Replace CCS811 Carbon Dioxide CO2 VOCs Air Quality Gas Sensor Module for Arduino 2PCS

I was able to get 5/6 of them running but one was completely DOA and board gets hot when power is applied. The other 5 seem to be doing ok.

I’m an irrepressible optimist, so I bought these despite the other reviews. However, at least one of my two were DOA as well. I haven’t tested the other yet, I came to the reviews to see if someone commented a different I2C address.

One of the two boards in this pack arrived DOA. Technically it worked, but it would frequently fail to initialize on the I2C bus if other things were plugged in. Not sure what the issue with it was. The other one worked perfectly. Normally for small boards like this I wouldn't care if some arrive dead, but it's kind of annoying since the little things were $10 each.
