Product Description
GY-BME280-3.3 is a breakout board that features a Bosch Sensortec ME280 sensor for measuring temperature, humidity and pressure.
The board has a jumper (solder link GS2) that allows selecting the I2C address, pull-up resistors (R2, R3) of 10k for the I2C bus, a 7-pin header with 2.54mm pitch, and two mounting holes of 3.5mm diameter.
The board’s default configuration is to use a single power rail for both Vdd and Vdd_IO (solder link GS1), and to have 0.1uF decoupling capacitors on both power supply pins.
If you want to use separate power rails for Vdd_IO (1.8V) and Vdd (3.3V), you need to remove the jumper GS1!
