Pinouts
- VIN: Voltage Supply Pin
- 3V3: 3.3v Regulator output
- GND: 0V Power Supply
- SCL: I2C Clock / SPI Clock
- SDA: I2C Data or SPI Data Input
- SDO/SAO: SPI Data output / I2C Slave Address configuration pin
- NCS: Chip Select for SPI mode only for MPU-9250
- CSB: Chip Select for BMP280
You only need to hook the 3.3 to VIN, the GND to GND and the SCL and SDA. The other connections are not needed.
