＊As of Sep 18, 2023 – we've updated this PCB with Adafruit Pinguin to make a lovely and legible silkscreen - you may get the new PCB or the older version with vector fonts - both are identical other than the fancy silkscreen.

If you've ever ordered and wire up a 9-DOF sensor, chances are you've also realized the challenge of turning the sensor data from an accelerometer, gyroscope and magnetometer into actual "3D space orientation"! Orientation is a hard problem to solve. The sensor fusion algorithms (the secret sauce that blends accelerometer, magnetometer and gyroscope data into stable three-axis orientation output) can be mind-numbingly difficult to get right and implement on low cost real time systems.
Bosch is the first company to get this right by taking a MEMS accelerometer, magnetometer and gyroscope and putting them on a single die with a high speed ARM Cortex-M0 based processor to digest all the sensor data, abstract the sensor fusion and real time requirements away, and spit out data you can use in quaternions, Euler angles or vectors.
Rather than spending weeks or months fiddling with algorithms of varying accuracy and complexity, you can have meaningful sensor data in minutes thanks to the BNO055 - a smart 9-DOF sensor that does the sensor fusion all on its own! You can read the data right over I2C and Bob's yer uncle.／借助 BNO055，您無需花費數周或數月的時間擺弄不同精度和複雜度的演算法，而是可以在幾分鐘內獲得有意義的感測器數據 - 這是一款智慧 9 自由度感測器，可自行完成感測器融合！你可以直接通過 I2C 和 Bob 的叔叔讀取數據。
【The BNO055 can output the following sensor data／BNO055可以輸出以下感測器資料】:
- 絕對方向 （歐拉向量，100Hz） 基於 360° 球體的三軸方向數據
- 絕對方向 （四元數，100Hz） 四點四元數輸出，可實現更精確的資料操作
- 角速度向量 (100Hz) 三軸“旋轉速度”，單位為 rad/s
- 加速度向量 (100Hz) 三軸加速度（重力 + 線性運動），單位為 m/s^2
- 磁場強度向量 (20Hz) 微特斯拉 (uT) 中的三軸磁場感測
- 線性加速度向量 (100Hz) 三軸線性加速度資料（加速度減去重力），單位為 m/s^2
- 重力向量 (100Hz) 三軸重力加速度（減去任何運動），單位為 m/s^2
- 溫度 (1Hz) 環境溫度（攝氏度）
- Absolute Orientation (Euler Vector, 100Hz) Three axis orientation data based on a 360° sphere
- Absolute Orientation (Quatenrion, 100Hz) Four point quaternion output for more accurate data manipulation
- Angular Velocity Vector (100Hz) Three axis of 'rotation speed' in rad/s
- Acceleration Vector (100Hz) Three axis of acceleration (gravity + linear motion) in m/s^2
- Magnetic Field Strength Vector (20Hz) Three axis of magnetic field sensing in micro Tesla (uT)
- Linear Acceleration Vector (100Hz) Three axis of linear acceleration data (acceleration minus gravity) in m/s^2
- Gravity Vector (100Hz) Three axis of gravitational acceleration (minus any movement) in m/s^2
- Temperature (1Hz) Ambient temperature in degrees celsius
Handy, right? So we placed this very nice sensor on its own breakout, complete with 3.3V regulator, logic level shifting for the Reset and I2C pins, an external 32.768KHz crystal (recommended for best performance), and breakouts for some other pins you might find handy. Comes assembled and tested, with a small piece of header. Some soldering is required to attach the header to the breakout PCB, but its pretty easy work. Best of all you can get started in 10 minutes with our handy tutorial on assembly, wiring, CircuitPython & Arduino libraries, and Processing graphical interface, and more!
最重要的是，您可以在 10 分鐘內開始使用我們關於組裝、接線、CircuitPython 和 Arduino 庫以及處理圖形介面等的便捷教學！
