H3LIS331DL Accelerometer Breakout Hookup
Guide
Introduction
The H3LIS331DL is a high-g accelerometer with I2C and SPI interface
options. It offers an adjustable output range of 100, 200, or 400g, and an
adjustable data rate of up to 1kHz.

Hardware Overview
The H3LIS331DL breakout is fairly simple.
H3LIS331DL Sensor IC
- This is the sensor IC. Its operating voltage only
extends up to
3.6V,
so to use it with a 5V Arduino or Arduino clone, you’ll
need some kind of voltage translation! It is perfectly centered on the PCB.

C Pull-up Resistors
- The board includes pull-up resistor so you don’t
need to add them externally.

C Pull-up Resistor Isolation Jumper
- If necessary, the I

C pull-up
resistors can be removed from the circuit by removing the solder from this
jumper.

C Header
- Most boards which can be
communicated to via I

C use this pinout, making it easy to stack them or
connect them in a daisy chain.
SA0 Jumper
- Closing this jumper changes the I
2
C address of the sensor
from 0x19 to 0x18.

CS Jumper
- Removing the solder from this jumper enables SPI mode.
When the part’s CS line is low at boot, it enables SPI mode.
SA0 Pin
- When the chip is in SPI mode, this goes from being the address
select pin to being the MISO pin.
CS Pin
- Chip select for SPI mode. Unused in I
2
C mode.
Interrupt Pins
- These pins are tied to interrupts that can be setup by the
software library to trigger on various conditions.
