Overview
The Arduino 9 Axes Motion Shield is based on the BNO055 absolute orientation sensor (datasheet) from Bosch Sensortec GmbH.
The BNO055 is a System in Package (SiP), integrating a triaxial 14-bit accelerometer, a triaxial 16-bit gyroscope with a range of ±2000 degrees per second, a triaxial geomagnetic sensor and a 32-bit microcontroller running the BSX3.0 FusionLib software.
The sensor features three-dimensional acceleration, yaw rate and magnetic field strength data each in 3 perpendicular axes.
It also provides the sensor fusion signals such as
- Quaternion
- Euler angles
- Rotation vector
- Linear acceleration
- Gravity vector
In addition, it incorporates an intelligent interrupt engine, which allows for triggering interrupts based on
- slow or no motion recognition
- any motion (slope) detection
- high-g-detection.
The shield is TinkerKit compatible, which means you can quickly create projects by plugging TinkerKit modules to the board.

Power
The Arduino 9 Axes Motion Shield has no power jack and is powered only when attached to an Arduino board.
Input and Output
The shield features several TinkerKit input/output and communication interfaces. Connecting TinkerKit modules can simplify the creation of a project or a prototype.
The on-board connectors are :
- 2 TinkerKit Inputs: IN2 and IN3 (in white), these connectors are routed to the Arduino A2 and A3 analog input pins.
- 2 TinkerKit Outputs: OUT5 and OUT6 (in orange), these connectors are routed to the Arduino PWM outputs on pins 5 and 6.
- 2 TinkerKit TWI: these connectors (4-pin in white) are routed on the Arduino TWI interface. Both connect to the same TWI interface to allow you to create a chain of TWI devices.
Physical Characteristics
The maximum length and width of the 9 Axes Motion Shield PCB are 2.7 and 2.1 inches respectively. Four screw holes allow the board to be attached to a surface or case. Note that the distance between digital pins 7 and 8 is 160 mil (0.16″), not an even multiple of the 100 mil spacing of the other pins.
Compatibility
The Arduino 9 Axes Motion Shield is compatible with Uno, Yùn, Leonardo, Ethernet, Mega and Due boards. When using the Arduino 9 Axes Motion Shield, be sure to solder the Interrupt bridge and Reset bridge in the correct position depending on the board used. See table:
| BOARD | INTERRUPT PIN | RESET PIN |
| Arduino Uno | D2 | D4 |
| Arduino Leonardo | D7 | D4 |
| Arduino Yun | D7 | D4 |
| Arduino Ethernet | D2 | D4 |
| Arduino Due | D2 | D4 |
| Arduino Mega | D2 | D4 |
| Arduino M0/M0 Pro | D7 | D4 |
For example to use 9 Axes Motion Shield with ArduinoUNO solder the Interrupt bridge on the pin D2.
Programming
The 9 Axes Motion Shield can be programmed with the Arduino software (download).
