Description
BME280 Temperature, Humidity and Pressure Sensor Module
GY-BME280 breakout board for measuring temperature, relative humidity and atmospheric pressure, with I2C and SPI interfaces.
- Source labels this board as a 5 V version and lists 1.8–5 V supply input; verify whether this specific board regulates power and shifts logic levels.
- BME280 chip limits per Bosch: VDD 1.71–3.6 V; VDDIO 1.2–3.6 V. Do not apply 5 V directly to the sensor chip pins.
- Interfaces: I2C (up to 3.4 MHz) and 3-/4-wire SPI (up to 10 MHz)
- Operating ranges: −40 to +85 °C; 0–100% RH; 300–1100 hPa
- I2C address: 0x76 with SDO low; 0x77 with SDO high
