## Description
|
||
|
||
**6-Axis IMU Unit** is a 6-axis attitude sensor with 3-axis gravity accelerometer and 3-axis gyroscope, which can calculate tilt angle and acceleration in real time. The chip adopts mpu6886, has 16 bit ADC, built-in programmable digital filter and on-chip temperature sensor, adopts I2C interface (addr:0x68) to communicate with host computer, and supports low-power mode.
|
||
