BMP280 - digital barometer, pressure sensor 110kPa I2C/SPI 3-5V - STEMMA QT - Adafruit 2651

Module with digital barometer from Bosch, it enables the pressure measurement in the range from 300 to 1100 hPa with the accuracy of 1 hPa. The system is based on technology piezoresistive what provides high accuracy and measurement stability.

The sensor operates with voltages rtanging from 3 V to 5 V. Pins are the holes for soldering the goldpin connectors with 2.54 mm pitch (included - for self-soldering). Straps enable the connection of the module with thewiresor the direct attachment to the breadboard. The board also has STEMMA QT / Qwiic connectors for easy connection. For proper operation, it is sufficient to connect power and I2C bus lines: of SDA data  and of SCL clock.
