Anyone playing with the Bosch BNO-055 units, with internal "sensor fusion" already built-in? I just received two of them and can't wait to solder the pins so I can tinker! Any comments about the device? They're a bit less than $35 for a Teensy 3.1 compatible board. I plan to use them with a Beaglebone Black. They are 3.3V units and use I2C. David Merchant
