The chip
What the ST LIS3DH actually is
Three-axis digital MEMS accelerometer supporting selectable measurement ranges, motion detection, orientation sensing, click detection and programmable interrupt generation. Designed for low-power motion sensing applications.
Wiring
How to connect the LIS3DH
The LIS3DH talks i2c at address 0x18 (up to 2 selectable addresses, handy when you need more than one on the same bus). It runs at 3.3–5 V, so match your host's logic level — if your host is 5 V and a board on the bus is 3.3 V-only, add a level shifter. Use the compatibility checker to confirm the exact cable for your setup.
Because the address is selectable, you can run several LIS3DH boards on one bus by setting each to a different address — no extra wiring beyond the shared SDA/SCL.
Wiring is the usual four: power, ground, SDA and SCL, plus pull-up resistors — almost always already fitted on the breakout. Nothing showing up? Run an i2c scan first; if the bus is silent, the 7-step checklist finds it faster than guessing.
Ecosystems
Plug-together options for the LIS3DH
LIS3DH breakouts ship with Qwiic and STEMMA QT — keyed 4-pin cables carrying power, ground, SDA and SCL, so there's nothing to solder and nothing to wire backwards. Chain it to the next board and keep going.
Running a mixed bench? Those ecosystems interoperate more than their marketing suggests — see every connector pairing for the cable or adapter you need, or the standards overview for how they compare.

Boards that clash with the LIS3DH
These want addresses the LIS3DH also answers (0x18, 0x19), so they can't share a bus with it untouched. If one is address-selectable, strap it elsewhere; if not, the conflict guide covers the multiplexer and second-bus routes, and the collision roundup explains why a scan won't warn you.

Questions
LIS3DH i2c FAQ
What is the LIS3DH's i2c address?
The LIS3DH uses 0x18 or 0x19, selected with an address pin or solder jumper on the board. If a scan turns up something unexpected, our i2c address list names the usual suspect for every address.
What voltage does the LIS3DH run at?
3.3–5 V logic. That range covers both 3.3 V and 5 V hosts, so it drops onto a Pi, ESP32 or Arduino without a level shifter.
Can I use two LIS3DHs on one i2c bus?
Yes — set each one to a different address (0x18, 0x19) using its address pin or jumper, then wire both to the same SDA/SCL. That gives you up to 2 on a single bus before you need a multiplexer.
Does the LIS3DH work with Qwiic and STEMMA QT?
Yes — LIS3DH breakouts ship with Qwiic / STEMMA QT, so it plugs straight in with no soldering. Mixing ecosystems? The compatibility checker gives you the exact cable or adapter.
