Important Notes

Do not connect the bare BMP280 chip directly to 5V logic — the chip operates at 1.71V–3.6V. Use a 3.3V regulator or a 5V-compatible breakout module with onboard level shifting.
When using I2C, connect CSB to VCC (or leave floating on modules with pull-up) to select I2C mode. Ground CSB to select SPI mode.
Set the I2C address by controlling the SDO pin: connect to GND for 0x76 (default on most modules) or to VCC for 0x77.
The sensor is factory-calibrated — no external calibration is required. Compensation coefficients are stored in internal OTP memory.
For outdoor use, enclose the sensor in a radiation shield or ventilated housing to protect from direct water ingress and direct sunlight.
Mount the sensor on vibration-dampening material when used in drones to reduce noise from motor vibrations.
Use the Bosch Sensortec API or official libraries for optimal readout and compensation calculations.
Store in anti-static packaging when not in use to prevent ESD damage.
