Adafruit 9-DOF Absolute Orientation IMU Fusion Breakout - BNO055

My project required a magnetometer for direction. I purchased QMC5883l to achieve accurate directions for my model boat. No matter how many times I tried to calibrate it to get right heading no success. The BNO055 worked right out of the box with the self-calibration feature. Now my navigation system works as expected. The sensor does have a feature where you can do some calibrations if needed but mine worked right out of the box! Incredible HIGHLY RECCOMEND!

This sensor is what I have been hunting for for years. I needed a simple heading and tilt indication for n indoor robot and all the other units I have tried are very difficult to get stable readings from without complex math calculations that many microcontrollers are not very good at. This unit resolves those issues and gives me very simple output in angles that can be immediately put to use. It's very finicky to get started up but once you get that nailed down it's dead simple to use.

If you are building a drone, flight computer, AHRS, or other project that requires accurate Eular or quaternion vectors, skip all the googling for equations and put this thing in "fusion mode" (see bno055 data sheet). The on board mcu will do all the heavy lifting work for you with great accuracy and speed! Another tip is to google up the Bosch videos and app notes rather than the hobby sites. They make it far easier to learn the chip and have a lot of libraries and instructions.

One of the best sensors I've come across. If you need position or orientation this is an excellent sensor for that. It's pricey but well worth it given the plug and play nature of this unit for getting the absolution orientation. We used it to stabilize a custom built drone. Building your own sensor from an accelerometer, gyro, and compass with signal processing and filtering would take a lot of effort to get right.

I had tried other 9D0F chips that just output the raw data of all the devices and that required running a Madgwick/Mahoney or similar fusion filter and I couldn't get them to provide stable heading, pitch, roll readings. I was up against a deadline (Halloween) to get it working. Saw this chip and glad I did. This chip already does all that and it is easy to calibrate by just holding it in various positions. Worked great and provides accurate stable readings at up to 100Hz rate.. Now if only my soldering skills were as good as this chip.

The euler angles and gravity-less acceleration data make this chip incredibly hands-off and useful for a wide array of applications. I am using it for an Arduino-based UAV flight controller and it takes a huge computation load off my microcontroller. I was even able to write matrix and vector libraries to combine this data into earth-frame acceleration data. The possibilities are endless! Adafruit includes this sensor as part of its unified sensor library - so it works almost right out of the box with a quick google search.

Good bang for your buck. Im actually very surprised at how accurate it is. 110% worth the money

Like all Adafruit breakout boards, the software support for Arduino is amazing and makes a very complex problem very approachable for the hobbyist. Following their clear tutorials, this novice was able to get this sensor working properly with no problems. Very little soldering required if you're using the headers, but you have the flexibility to put them on or not.
