The chip
What the Kionix KX132 actually is
Three-axis digital MEMS accelerometer with 16-bit resolution, ranges to ±16 g, a large internal FIFO buffer, and hardware engines for wake-up, directional-tap and free-fall detection — built for low-power motion applications.
Wiring
How to connect the KX132
The KX132 talks i2c at address 0x1E (up to 2 selectable addresses, handy when you need more than one on the same bus). It runs at 1.7–3.6 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 KX132 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 KX132
KX132 breakouts ship with Qwiic — 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 KX132
These want addresses the KX132 also answers (0x1E, 0x1F), 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
KX132 i2c FAQ
What is the KX132's i2c address?
The KX132 uses 0x1E or 0x1F, 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 KX132 run at?
1.7–3.6 V logic. It's 1.7 V-only — driving it straight from a 5 V Arduino risks damage, so level-shift first.
Can I use two KX132s on one i2c bus?
Yes — set each one to a different address (0x1E, 0x1F) 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 KX132 work with Qwiic?
Yes — KX132 breakouts ship with Qwiic, so it plugs straight in with no soldering. Mixing ecosystems? The compatibility checker gives you the exact cable or adapter.
