Connection
- VIN. Power supply: 5V
- 3V3. Power supply: 3.3V
- GND
- SCL. I2C Clock or SPI clock
- SDA. I2C Data or MOSI pin for SPI
- SDO/ SAO. Address adjust pin
- NCS. Select only MPU-9250
- CSB. Select only bMP-280.
I2C is appropriate for peripherals where simplicity and low manufacturing cost are more important than speed.
Connect to Arduino
Arduino pins 4 and 5 are hardwired, see https://stackoverflow.com/questions/57582626/changing-wire-librarys-hardware-i2c-pins-for-custom-arduino#57582678
Arduino Board has SCL and SDA pins on the digital side. Those pins work too.
