1pcs BMP280 3-3V Digital Barometric Pressure Altitude Sensor High Precision Atmospheric Module IIC I2C Board GY-BMP280

GY-BME280-3.3V high precision atmospheric pressure sensor module Altimeter   The BME280 is a breakout board with Bosch Sensortec ME280 temperature, humidity and pressure sensors. The board has an optional I2C address jumper (weld link GS2), I2C pull-up resistor, 7-pin connector 2.54mm and two mounting holes 3.5mm. Board default settings; single power line Vdd = Vdd_IO (solder link GS1), pull-up resistor (R2, R3) 10k, protocol selector resistor 0ohm (R1), decoupling capacitor 0.1uF on both supply pins Vdd and Vdd_IO . If you connect the board to two power rails, VDD_IO 1.8V and VDD 3.3V, be sure to remove the power rail jumper GS1!
