We have released a new product, the BerryIMU-320G, which is an inertial measurement unit, or IMU, that measures and reports on velocity, orientation, shock events and gravitational forces using a combination of two accelerometers, a gyroscope, a magnetometer and a barometric/altitude sensor.
At the heart of BerryIMU-320G is ST’s LSM6DSV320X, a smart 6-axis IMU that integrates one gyroscope and two separate accelerometers on the same die:
- a low-g accelerometer for precise everyday motion sensing (tilt, orientation, vibration), and
- a high-g accelerometer capable of measuring extreme impacts up to ±320 g.
This means BerryIMU-320G can capture fine movements and violent shocks with one device, without needing a separate high-g sensor. The low-g channel provides high resolution and low noise for normal motion, while the high-g channel is reserved for crashes, drops and other intense events. Because they are independent, saturating the high-g accelerometer does not disturb the low-g readings, so you don’t lose detail on everyday motion while still being able to catch rare extreme impacts.
BerryIMU-320G is also fitted with a Bosch BMP581 barometric pressure sensor which can be used to calculate altitude & temperature , and a LIS3MDL magnetometer for heading/compass measurements. Temperature readings are available from the on-board sensors.
