The Circuit Playground Express has at its center the LIS3DH 3-axis XYZ accelerometer. Some of its features:
- Three axis sensing, 10-bit precision
- ±2g/±4g/±8g/±16g selectable scaling
- Multiple data rate options 1 Hz to 5Khz
- Tap, Double-tap, orientation & freefall detection
More detail can be found in datasheets and more.
Different accelerometers have separate features. Some have additional bits of precision or additional scaling options but for the price, the LIS3DH provides features most folks will want to implement their projects.
If your project needs differing features, here are some that you may wish to use in your projects other than the LIS3DH depending on differing capabilities:
