Hi I am new to IMU sensors, I am using BRKT-STBC-AGM01 breakout board and trying to interface my MCU with the board. I am confused regarding the pin connections.
first I am trying to interface Gyro sensor using I2C - FXAS21002C, later I will be interfacing FXOS8700C.
The pin connections I have used for Gyroscope
Sensor Pin MCU Pins
Am I missing anything else regarding pin connections? I haven't used interrupt pins yet. I want to operate the sensors in active mode.
Kindly guide me
Please see below the schematic and pinout diagram.
So you need to connect the following pins to your MCU:
SCL1 - J3.4
SDA1 - J3.5
VDD_21002 - J3.7
VDDIO_21002 - J3.9
GND - J4.5
RST_21002 - J4.7 - connect to VDDIO_21002 if not used by your MCU
Note that the default 7-bit I2C slave address is 0x20 as SA0_MISO pin is tied to GND.

Hope it helps.
