Adafruit ICM-20649 Wide Range ±30g ±4000dps 6-DoF IMU - STEMMA QT / Qwiic

Product ID: 4464

Most accelerometers have a similar range of measurements that they can make: often around 2G - 16G. Similarly, most gyros can measure in the range of 250 degree/s to 2000 degrees/s. That's enough for many situations, however, there are many situations where it's not quite enough. When measuring things like a golf swing, soccer ball kick or perhaps a fancy racing car,...
