Description
ME-BME280 is a breakout board stealing abosch Sensortec ME280 temperature, humidity and pressure sensor.
Board has selectable I2C address jumper (solder link GS2), I2C pull-up resistor, 7-pin header 2.54mm, and two mounting holes 3.5mm.
Board default setting Single Power Rail VDD = VDD_IO (Solder Link GS1), Pullup Resistance (R2, R3) 10K, Protocol Selector Resistance 0Ω (R1), Disconnect 0.1UF in both power supplies.
When the board is connected to both power rails, remove the power rail jumper GS1 to both VDD_IO 1.8V, VDD 3.3V.
BME280 Features:

BOSCH has expanded the game with the new BMP280 sensor, temperature environmental sensor, and environmental sensor upgraded to BMP085 / BMP180 / BMP183 with the next generation of pressure pressure. This sensor is perfect for all kinds of weather senses and can be used in both I2C and SPI.
This precision sensor from Bosch is the best low cost, precision detection solution for measuring pressure with ±1 HPA absolute accuracy, and temperature with accuracy of ±1.0 degrees Celsius. It can also be used as an altimeter with a accuracy of ±1 meter as the pressure changes and pressure measurement is very good.
BME280 is the next generation of sensors from Bosch and upgraded to BMP085 / BMP180 / BMP183 with low altitude noise 0.25M and has the same high speed conversion time. Same specifications, but can be used with either I2C or SPI. Go with i2c for easy wiring. If you want to connect a bundle of bundles without worrying about I2C address collision, please go to SPI.
