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.

Connection

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.
