MPU9250 9-axis sensor

The 9-axis sensor, MPU9250, is placed on the BPI:bit board. and MPU9250 uses I2C 0x69 address.

The 9-axis is the combination of 3 separate triple axis sensors. For more detailed information of this chip, click here MPU 9250 datasheet to view the datasheet.\

BPI:bit power

When you use BPI:bit, you need to supply the board first, and the bit supports three power supply modes

  • 1.micro USB port:USB cable power supply, the design of BPI:bit board has Micro USB interface, which is quite common in daily life and is quite convenient to use.
  • 2.Battery port:Through 2 pin battery power supply socket, can through the lithium battery, battery pack to power supply board, interface fool proof design, don't worry about the power supply through the 2 pin battery power supply socket, can through the lithium battery, battery pack to power supply board, interface fool proof design, don't have to worry about power supply meet the problem.
  • 3.Goldfinger ：Power is supplied through the gold finger, and the gold finger at the bottom of the board contains the power interface. Meanwhile, it has both input and output functions and has high compatibility.
