Serial 6-Axis Accelerometer/Gyroscope Module for Arduino Wiki

Introduction

This module integrates high-precision gyroscopes, accelerometer, microprocessor of high-performance and advanced dynamics solves and Kalman filter algorithms that aim to quickly solve the current real-time movement of the module attitude. The use of advanced digital filtering technology can effectively reduce measurement noise and improve accuracy.
The module comes with built-in gesture solver that can get accurate attitude in dynamic environment combining with dynamic Kalman filter algorithm. Its static measurement accuracy is up to 0.05 degree(dynamic 0.1) with high stability, which could bring better performance even than some professional Inclinometers!
There is a voltage stabilizer circuit inside the module. The product should be operated at 3.3-5V and its pin level is compatible with 3.3/5V embedded systems. It employs TTL interface for connection.

Specification

Voltage: 3.3V~5V
Current: <40mA
Size: 51.33610mm
Measuring Dimension: acceleration: 3D; angular velocity: 3D; attitude angle: 3D
Range: acceleration: ±2/4/8/16g(optional); angular velocity: ±250/500/1000/2000 °/s(Optional), attitude angle: ±180°
