The Adafruit LIS3DH is a popular, low-power triple-axis accelerometer breakout packed with features typically found only on higher-end sensors. With selectable measurement ranges, multiple interface options, and built-in motion detection, it's one of the most versatile accelerometers available at this price point.

This breakout includes an onboard 3.3 V regulator and level shifting, so it works safely with both 3.3 V and 5 V systems — no external level shifter needed. It communicates over I2C or SPI, with an address selection pin allowing two sensors on the same I2C bus.

Key Features

• Triple-Axis Sensing – 10-bit precision across X, Y, and Z axes
• Selectable Range – ±2g, ±4g, ±8g, or ±16g measurement scaling
• Dual Interface – I2C (two possible addresses) and SPI support
• Ultra-Low Power – As low as 2 µA current draw from the chip
• Configurable Data Rates – From 1 Hz to 5 kHz
• Built-in Detection – Tap, double-tap, orientation, and freefall events via interrupt output
• 3 Additional ADC Inputs – Readable over I2C for extra analogue sensing
• 3.3 V and 5 V Compatible – Onboard regulator and level shifting for Arduino, Raspberry Pi, Feather, and more

Ideal For

• Motion and orientation sensing projects
• Tap and gesture detection
• Wearable electronics and activity tracking
• Freefall and impact detection systems
