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.

Connection
