The LIS3DH is a very popular low power triple-axis accelerometer. It's low-cost, but has just about every 'extra' you'd want in an accelerometer:
- Three axis sensing, 10-bit precision
- ±2g/±4g/±8g/±16g selectable scaling
- Both I2C (2 possible addresses) and SPI interface options
- Interrupt output
- Multiple data rate options 1 Hz to 5Khz
- As low as 2uA current draw (just the chip itself, not including any supporting circuitry)
- Tap, Double-tap, orientation & freefall detection
- 3 additional ADC inputs you can read over I2C
To all that, we've also added:
- 3.3V regulator + level shifting, so you can safely use with any Arduino or microcontroller without the need for an external level shifter!
We kept seeing this accelerometer in teardowns of commercial products and figured that if it's the most-commonly used accelerometer, its worth having a breakout board!
This sensor communicates over I2C or SPI (our library code supports both) so you can share it with a bunch of other sensors on the same I2C bus. There's an address selection pin so you can have two accelerometers share an I2C bus.
