## 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.

## Product Features

- 3-axis gravity accelerometer and 3-axis gyroscope
- On chip temperature sensor
- 1KB FIFO
- Support low power consumption
- Development platform: Arduino, uiflow (blocky, python)
- 2X LEGO compatible holes

## Include

- 1x 6-Axis IMU Unit
- 1x Grove Cable (5cm)

## Application

- Wearable devices
