Introduction
GY-91 or OKY3259-1 includes BMP280 and MPU-9250 chips.
Accelerometer, gyroscope, magnetic field, pressure, (temp?) Includes Bosch BMP280 sensor [1] for pressure and temperature and MPU-9250 for inertia[2].

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.
