Serial 6-Axis Acceleration Sensor for Arduino

This attitude module from DFRobot combines a gyroscope and an accelerometer with a microcontroller that calculates the attitude itself with a Kalman filter. It provides acceleration, angular velocity and attitude angle in three axes via a serial TTL interface (UART). According to DFRobot it reaches an accuracy of 0.05° static and 0.1° dynamic. A voltage regulator in the housing allows operation at 3.3 V and 5 V.

Features:

• Attitude angle ±180° directly from the module
• Selectable measuring ranges for acceleration and rotation rate
• Data output from 0.1 Hz to 200 Hz
• Baud rate adjustable from 2400 to 921600 baud
• Housing with mounting tabs, cable included

Application Examples:

• Attitude and inclination of robots and platforms
• Self-balancing robots
• Recording of movements
