{{BME280-NAV}}
{{traduction}}
You can easily wire this breakout to any microcontroller, we'll be using an Arduino. For another kind of microcontroller, as long as you have 4 available pins it is possible to 'bit-bang SPI' or you can use two I2C pins, but usually those pins are fixed in hardware. Just check out the library, then port the code.
== Brancher en I2C ==
Use this wiring if you want to connect via I2C interface
* Connect '''Vin''' to the power supply, 3-5V is fine. Use the same voltage that the microcontroller logic is based off of. For most Arduinos, that is 5V
* Connect '''GND''' to common power/data ground
* Connect the '''SCL''' pin to the I2C clock SCL pin on your Arduino. On an UNO & '328 based Arduino, this is also known as '''A5''', on a Mega it is also known as digital 21 and on a Leonardo/Micro, digital 3
* Connect the '''SDA''' pin to the I2C data SDA pin on your Arduino. On an UNO & '328 based Arduino, this is also known as '''A4''', on a Mega it is also known as digital 20 and on a Leonardo/Micro, digital 2
By default, the i2c address is 0x77. If you add a jumper from SDO to GND, the address will change to 0x76.

== Brancher en SPI ==
Since this is a SPI-capable sensor, we can use hardware or 'software' SPI. To make wiring identical on all Arduinos, we'll begin with 'software' SPI. The following pins should be used:
* Connect '''Vin''' to the power supply, 3V or 5V is fine. Use the same voltage that the microcontroller logic is based off of. For most Arduinos, that is 5V
* Connect '''GND''' to common power/data ground
* Connect the '''SCK''' pin to Digital #13 but any pin can be used later
* Connect the '''SDO''' pin to Digital #12 but any pin can be used later
* Connect the '''SDI''' pin to Digital #11 but any pin can be used later
* Connect the '''CS''' pin Digital #10 but any pin can be used later
Later on, once we get it working, we can adjust the library to use hardware SPI if you desire, or change the pins to other
