The LIS3DH is a high performance, ultra-low power, three-axis linear accelerometer. It features user-selectable scales up to 16g, an embedded temperature sensor, 10-bit ADC and a standard digital I2C/SPI serial interface.
Parallax Inc. places the LIS3DH on a compact 20x21 mm PCB with an 8-pin straight header. The I/O connections operate at the same voltage supplied to the VIN pin for compatibility with both 3.3 V and 5 V microcontrollers. The Parallax module includes a low-noise 2.5 V regulator which matches the LIS3DH factory calibration voltage for the highest possible accuracy.
This LS3DH module is supported by the latest Propeller C libraries as well as dedicated BlocklyProp Solo blocks for easy visual programming.
