Adafruit ISM330DHCX 6 DoF IMU Breakout Board

Adafruit ISM330DHCX 6 DoF IMU Breakout Board is based on the STM ISM330DHCX, an industrial quality accelerometer, and gyroscope 6-DOF Inertial Measurement Units ( IMUs). This IMU sensor has 6 degrees of freedom - 3 degrees each of linear acceleration and angular velocity at varying rates within a respectable range. The accelerometer has a ±2/±4/±8/±16g at 1.6Hz to 6.7KHz update rate. For the gyroscope, the update rate is ±125/±250/±500/±1000/±2000/±4000dps at 12.5Hz to 6.7KHz. This sensor has extra calibration and compensation circuits to give it excellent performance in a wide environmental range from -40 to +105°C. The accelerometer and gyroscope are on the same silicon die, which will keep the 6 measurements synchronized better than when the two sensors are on separate dies.

The sensor includes built-in tap detection, activity detection, pedometer/step counter, and a programmable finite state machine/machine learning core that can perform some basic gesture recognition. For interfacing, the user can use either SPI or I²C, and there are two configurable interrupt pins. For advanced usage, the user can attach additional devices to an external I²C/SPI port, which is used for optical image stabilization. The sensor has been placed on a compact breakout board with voltage regulation and level-shifted inputs. That allows the user to use them with 3V or 5V power/logic devices.

Adafruit also wrote libraries to help users get these sensors integrated with Arduino/C++ or CircuitPython/Python boards such as Raspberry Pi or other single board computers. Since the I²C interface is included, the user can easily connect it up with two wires. The SparkFun qwiic compatible STEMMA QT connectors are included for the I²C bus, so there is no need to solder. The user just wires up to their favorite microcontroller, like the STM32F405 Feather, with a plug-and-play cable to get 6 DoF data right away.
