Automation, sensing and robotics • BNO08x MicroPython Library for I2C, SPI, & UART. Integrated 9-axis IMUs with fusion

Release of efficient Micropython code for BNO086, BNO085, BNO080 that can run at 400-500Hz (2.5ms to 2.0ms).

Some of the features that this code supports:

• Timestamp and accuracy on each sensor reports

• Enable sensor report frequency (period) and verification of what sensor will provide

• SPI & UART at 3 Mbit/s, I2C at 400 KBaud

• Euler conversion functions for Quaternions

• Time stamps correlated with host

• Calibration and Tare functions

• Int pin for fast report update notification

• Reliable hardware reset with reset pin
