Alternative Driver (Python)

If you are using this breakout with a Raspberry Pi or Pi2, you can also look at the Adafruit_Python_BME280 driver.

This alternative driver uses I2C to communicate with the BME280, so connect SCL on the Pi to SCK on the BME, and SDA to SDI, along with power (3.3V to VIN) and GND.
