OVERVIEW
GebraBit ICM20789 is a 7-axis, High-Performance module that integrates 6-axis Inertial which combines a 3-axis gyroscope, 3-axis accelerometer with 16-bit ADC, and Barometric Pressure Sensor with 24-bit ADC.
GebraBit ICM20789 operates with a 5V input Supply Voltage due to an integrated 1V8 regulator, which regulator output is accessible on the “1V8” pin.
User can interface with GebraBit ICM20789 by either I2C or SPI protocol. This is achieved by dedicated four jumper selectors on the top right of the GebraBit ICM20789 module. Furthermore, the last jumper selector (Fifth) is considered for setting the I2C address.
Another important issue of the module is accessing the I2C interface of the ICM20789 pressure sensor, by PR SDA and PR CLK pins, the user also has access to FSYNC and INT pins.
The pressure sensor’s MEMS capacitive architecture provides the industry’s lowest noise at the lowest power, high sensor throughput, and temperature coefficient offset of ±0.5 Pa/°C. The pressure sensor’s combination of high accuracy elevation measurements, low power, and temperature stability complemented by the motion tracking 6-axis inertial sensor in a small footprint, make it ideal for a wide range of motion tracking applications. The embedded 6-axis MotionTracking device combines a 3- axis gyroscope, 3-axis accelerometer, and a Digital Motion Processor™ (DMP). An available large 4 kB FIFO reduces traffic on the serial bus interface, and power consumption through burst sensor data transmission. The Gyroscope has programmable FSR of ±250 DPS, ±500 DPS, ±1000 DPS, and ±2000 DPS. The Accelerometer FSR is programmable to ±2g, ±4g, ±8g, and ±16g.
