Everything ok. Default I2C address for BMP280 is 0x77. This version is running on 0x76 address according to I2C scanner, so you must change the library in order to work.Temp./Humidity sensor on board is HDC1080, not SI7021.

This breakout works well but this is not the version with Si7021. It is with the HDC1080. This is good for temperature en humidity so but this is not the same programming way. Please notice it !!!

Very satisfied with readings with the help of a Wemos D1-mini module working fine over wifi and after flashing with Tasmota gives me nice graphics in Domoticz v2020.2

+ CO2e+pressure+temperature+humidity in one device - really used HDC1080 for t/h, not SI7021 - not so easy to use (need find libs, rewrite code for CCS811 etc) - sometimes shows strange results for all parameters, probably need some calibration

A very powerful product, however a bit difficult to burn-in and program in connection with an Arduino nano

Good for experiment and of course to measure. Will use it in indoor air quality testing.

Cool breakout. But its hard to easy find libraries for Arduino that supports all of the three sensors.

It came fast, it looks normal. I have not tried to include:-).

Пришло быстро, выглядит нормально. Включать ещё не пробовал :-).
