BME280 is a small package low power digital composite sensor based on APSM process, it can measure ambient temperature and atmospheric pressure. The air pressure sensing element is a low-noise, high-precision, high-resolution absolute atmospheric pressure piezoelectric sensing element; the temperature sensing element has the characteristics of low noise and high resolution, and the temperature value can perform temperature compensation and self-correction on the air pressure. By configuring the sampling rate register, the sampling rate of the sensitive element can be set. Ideal for mobile devices with limited space, such as smartphones, tablets, smart watches and wearables, weather forecasts, vertical speed indications, flight control devices, indoor and outdoor navigation, smart home devices.
High precision GY-BMP280 atmospheric pressure sensor module for accurate air pressure measurement, with a measurement range of 300 ~ 1100hPa and an error of ±1hPa, providing reliable data for Arduino projects and other applications, Small and power-efficient BMP280 sensor offering a temperature measurement range of 0℃～65℃, with an error within ±0.5°C ±1°C, making it ideal for GPS modules, watches, and other battery-operated devices requiring high performance and low power consumption.
Versatile digital atmospheric air pressure sensor with IIC or SPI interface options, M3 fixing screw holes for easy installation and fixing, and a resolution of 0.16Pa for air pressure measurement and 0.01°C for temperature measurement, suitable for various indoor and outdoor navigation, weather forecast, and sports application, BMP280 sensor supports new filter modes and SPI interface in a compact size, offering high performance in all applications requiring accurate pressure measurement, making it perfect for enhancing GPS navigation, indoor navigation, weather forecast, and vertical velocity indication.

I've only used 2 of the boards so far; they are both working well and very close to one another in calibration (which is good, since they're being used in a differential sensor). One nice feature of these breakout boards is the ability to easily change the I2C address between 0x76 and 0x77 based on whether the SDO pin is tied low (default via onboard pull-down) or high. Very useful for applications like mine when both differential sensors are on the same bus.

I tried five of the ten. I used them unsoldered, with soldered headers, and with hammer headers.None of the first five worked. I got my money back and threw all ten away.

All of them worked and worked pretty well. No DOA parts.Averaging the output stream over a three-second interval made the result agree with my reference gauge to within ±3ft over 30k feet.

Easy to install and works fine with Meshtastic on my LoRa system. Easy to install on a Heltec Wireless Stick.

All sensors read about 10 degrees (F) high. Four out of ten have failed since initial installation.

These work well, and worked without issues. They let you easily change the address too, unlike some other boards which are a pain to deal with. Accuracy/precision is alright, nothing amazing but great for a basic temp monitor.

So far I've tested 3 of them and they all work correctly over I2C hooked up to an ESP8266 D1 Mini v4 Type-C running ESPHome v2023.6.5. Compared to the BME280 these seem to read about 1 hPa / 0.3-0.5 C higher.The default address for these modules is 0x76, If you need 0x77 connect SDO (Pin 6) to Vcc.

The units arrived individually packaged. All of them work as expected. Readings were pretty accurate and worked great for my DIY project
