Seeed 原廠 Grove - 6-Axis Accelerometer&Gyroscope 6軸加速度計和陀螺儀 (BMI088) (101020584)
DESCRIPTION
The Grove - 6-Axis Accelerometer&Gyroscope(BMI088) is a 6 DoF(degrees of freedom) High-performance Inertial Measurement Unit(IMU) .This sensor is based on BOSCH BMI088, which is a high-performance IMU with high vibration suppression. The 6-axis sensor combines a 16 bit triaxial gyroscope and a 16 bit triaxial accelerometer. Specially, you can use this sensor on the drone and robotics application in demanding environments.
Features
- The BM1088 is designed for drones, robotics and industry applications with challenging performance requirements.
- Wide acceleration measurment range(up to 24g)
- The accelerometer features a low TCO of 0.2 mg/K and low spectral noise of only 230 pg/sqrt(Hz) in the widest measurement range of ± 24 g
Typical Applications
- Drones and flying toys
- Industrial robots, hover boards
- Domestic applications(e.g. vacuum cleaner, social robots,etc.)

Power
The operating voltage range of BMI088 is 2.4-3.6V, so we use the XC6206P30 chip to provide a stable 3.0V. The input of XC6206P30 ranges from 1.8V to 6.0V, so you can use this module with your Arduino both in 3.3V and 5V.
Bi-directional level shifter circuit
This is a typical Bi-directional level shifter circuit to connect two different voltage section of an I2C bus. The I2C bus of this sensor use 3.3V, if the I2C bus of the Arduino use 5V, this circuit will be needed. In the schematic above, Q1 and Q2 are N-Channel MOSFET CJ2102, which act as a bidirectional switch. In order to better understand this part, you can refer to the AN10441
