[Dprglist] BNO-055 and the Rpi

[Ross Melbourne]

Hi Doug,
In case it is helpful, I used the https://cdn-learn.adafruit.com/downloads/pdf/bno055-absolute-orientation-sensor-with-raspberry-pi-and-beaglebone-black.pdf <https://cdn-learn.adafruit.com/downloads/pdf/bno055-absolute-orientation-sensor-with-raspberry-pi-and-beaglebone-black.pdf> tutorial to make the BNO055 work with a Pi.
