GY-BMP280-3.3 Precision Altimeter Atmospheric Pressure Sensor Module

GY-BMP280-3.3 Precision Altimeter Atmospheric Pressure Sensor Module

Important Note

• The BMP280 does not measure humidity
• It measures temperature, pressure, and altitude only
• If using separate VDDIO (1.8V) and VDD (3.3V), remove the GS1 power rail jumper
