IMU1 Module with MikroBus Interface

The Black Oak Engineering IMU1 Module with MikroBus interface (#BE-KIM1) provides an accurate 3-axis accelerometer, 3-axis rotation gyrometer, and a 3-axis magnetometer, on a simple, standardized PCBA module. Either IIC, SPI, UART, or UART-RVC may be used to communicate with it. The IMU1 incorporates technology from Black Oak Engineering, Bosch Sensortec, Ceva DSP, and Hillcrest Labs. A highly stable 32768 Hz oscillator clock source is included. The Bosch / Ceva BNO085 is primarily intended for use in mobile devices. However, it is far simpler to develop with and use on the MikroBus platform. The SensorNet API is well documented and available freely from Ceva. As always, BOE is available for value-added support.
 
It has a wide operating temperature range of -40 to +85 °C (-40 to +185 °F). 
 
MikroBus is a common, convenient interface form factor. The IMU1 requires only the RST, 3V3, Gnd, and communication signal lines. There are two rows of eight sockets, 100-mil (2.54 mm) separation, 900 mil (22.86 mm) row to row. Board is 1.1 x 1.3 inch (28 x 33 mm).

Humidity / water exposure. The PCBA does not include a protective enclosure. Nor is it confor mally coated. Condensing humidity and water exposure must be completely avoided.
The nearby presence of metallic structures may affect the magnetometer.
