Engineering inferenceOn-chip sensor fusion outputs orientation directly — no fusion filter to run on the host.
Engineering inferenceNo-load speed, rated performance and stall limits describe different operating points. A stall specification is not a continuous operating rating.

What it measures, how fast, and how the controller reads it.
| Pin / wire | Position | Role | Notes |
|---|---|---|---|
| SO | spi miso | This is an output pin for POCI (Peripheral Out, Controller In). The device sends data to the controller on this line. This is also connected to the I 2 C's SDA and UART's TXO pin. | |
| SI | spi mosi | This is an input pin for the PICO (Peripheral In, Controller Out). Device receives data from the microcontroller on this line. This is also connected to the address jumper. Tie to 3.3V to change I 2 C address from 0x4A to 0x4B . | |
| SCK | spi sck | This is an input for the SPI clock. This is also connected to the I 2 C's SCL and UART's RXI pin. | |
| CS | spi cs | This is an input for the SPI chip select pin and active low. It is used to as a clock signal to synchronize controller and peripheral. <<Table 9_5>> | | |---| <<END Table 9_5>> [image p009_img6.jpg: SPI] The protocol selection is set for I 2 C by default. You will need to adjust the jumpers on the back of the board for SPI. For more information, check out the section about the jumpers. | |
| TXO | uart | This is an output pin for serial UART transmit pin. Data is sent out to the microcontroller to this pin. This is also connected to the I 2 C's SDA and SPI's POCI pin. | |
| RXI | uart | This is an input pin for the serial UART receive pin. Data is received from the microcontroller to this pin. This is also connected to the I 2 C's SCL and SPI's SCK pin. <<Table 9_6>> | | |---| <<END Table 9_6>> [image p009_img7.jpg: Serial UART] The protocol selection is set for I 2 C by default. You will need to adjust the jumpers on the back of the board for the serial UART. For more information, check out the section about the jumpers. ### Reference Axis For easy reference, we've documented the IMU's vectors with 3D Cartesian coordinate axes on the top and bottom side of the board. Make sure to orient and mount the board correctly so you know which way the BNO086's data is pointing. Remember, it's all relative. <<Table 9_7>> | | | |---|---| <<END Table 9_7>> [image p009_img8.jpg: Reference Axis on the Top Side] [image p009_img9.jpg: Reference Axis on the Bottom Side] ### LED There is one LED on the board. The LED lights up when the board is powered with 3.3V. There is a jumper on the back if you decide to disable the LED. <<Table 9_8>> | | |---| <<END Table 9_8>> [image p009_img10.jpg: LED] ### Miscellaneous Pins Below are some additional pins that are broken out for the BNO086. | |
| RST | reset | The reset signal pin is an input pin and it is active low. Pull it low to reset the IC. You can find this on both sides of the board. | |
| INT | interrupt | The interrupt pin is an output pin and active low. When BNO080 is ready for communication, it will pull this pin low. | |
| WAK | other | The wake signal pin is an input pin and it is active low. Pull it low to wake the BNO086's processor from sleep mode. | |
| BOOT | other | The BOOT pin next to the Qwiic connector is necessary for configuration of the communication mode. If the BOOT pin is low upon reset or power up, the chip will go into bootloader mode to allow for programming of new firmware. <<Table 9_9>> | | |---| <<END Table 9_9>> [image p009_img11.jpg: Miscellaneous Pins] ### Jumpers There are a few jumper pads available on the top and bottom of the board. Most of the jumpers are on the bottom. For more information on modifying the jumpers, check out our tutorial on working with jumper pads and PCB traces . |

Ranges are the largest selectable full-scale setting; noise densities are typical datasheet values.
No-load, rated-load and stall figures retain their separate test conditions.
Stall torque and current are not continuous ratings. Check the duty cycle and starting load when choosing the driver and power supply.
Product operating conditions, chip ambient ratings, package case limits and junction maxima remain separate.
Reported product dimensions may exclude protruding components. Unknown height does not establish a complete clearance envelope.
Attached generated geometry is an approximate envelope. A generated outline does not establish an electrically verified PCB footprint.
