Frequently Asked Questions

What is the default I2C address and how can I change it?

The default I2C address is 0x19. The module includes a physical toggle switch that allows you to change the address to 0x18 if needed to avoid conflicts with other I2C devices on the same bus. Ensure your microcontroller code references the correct address after switching.

What is the power consumption in different operating modes?

In its ultra-low-power mode, the sensor draws only 8–10 µA, making it ideal for battery-powered projects. For higher performance with lower noise, you can switch to high-performance mode, which consumes approximately 0.12 mA. The output data rate and internal filters also affect overall current draw.

How do I connect this sensor to an Arduino or Raspberry Pi?

Use the included Gravity-4P connector cable. Connect the module's VCC (red wire) to 3.3V or 5V, GND (black) to ground, SDA (blue) to the I2C data line, and SCL (green) to the I2C clock line on your board. No soldering is required. Ensure your platform's I2C pins are correctly enabled in software.

Can this sensor detect free-fall, taps, and orientation?

Yes. The LIS2DW12 has a dedicated internal engine and two programmable interrupt pins. You can configure it to detect events like free-fall, 6D/4D orientation (portrait/landscape), single or double taps, and general motion/stillness. This offloads processing from the main MCU and allows for smart wake-up from sleep.

What is the significance of the 10,000g shock survivability rating?

This rating indicates the sensor can withstand mechanical shocks up to 10,000 times the force of gravity without permanent damage or calibration shift. This high robustness makes it suitable for applications in demanding environments like industrial machinery monitoring, sports equipment, or automotive systems where high-g impacts may occur.
