BME280 breakout board e-BoB (160109-1)

Little breakout board for the Bosch Sensortec BME280 Environmental sensor supporting I²C and SPI. Selecting the interface is done with 0R jumper resistors.

Connecting SDO to GND results in slave address 0x76 (R4 open, R5 mounted); connecting it to VDDIO results in slave address 0x77 (R4 mounted, R5 open).

The stuffing table below resumes all the options.

The BME280 can be powered from 1.71 V to 3.6 V. Its interface has its own supply pin V_DDIO allowing voltages from 1.2 V to 3.6 V. R1 connects V_DD to V_DDIO. Remove R1 when interfacing the module to levels that are not the same as the supply voltage.

I2C (0x76)	I2C (0x77)	SPI
R1 = 0R	R1 = 0R	R1 = 0R
R2 = 10k	R2 = 10k	R2 = NC
R3 = 10k	R3 = 10k	R3 = NC
R4 = NC	R4 = 0R	R4 = NC
R5 = 0R	R5 = NC	R5 = NC
R6 = NC	R6 = NC	R6 = 0R
R7 = 0R	R7 = 0R	R7 = NC
R8 = NC	R8 = NC	R8 = 0R

A driver for the BME280 can be found at its Elektor Labs GitHub page.
