STMicroelectronics STEVAL-MKI009V1

Overview

STEVAL-MKI009V1 from STMicroelectronics is a ready-to-use adapter board built around the LIS3LV02DL 3-axis digital output linear accelerometer, designed for direct plug-in evaluation into standard DIL-20 sockets. It provides full pin access, on-board 10 µF + 100 nF VDD decoupling, and mechanical compatibility with other ST sensor adapter boards for rapid sensor interchange during prototyping.

For engineers reviewing the STEVAL-MKI009V1 datasheet, STEVAL-MKI009V1 pinout, STEVAL-MKI009V1 application, or STEVAL-MKI009V1 equivalent, this board enables immediate LIS3LV02DL integration without custom PCB design-ideal for motion-sensing validation in handheld devices, industrial tilt detection, and embedded vibration monitoring.

Technical Context

The board implements a passive DIL-20 socket interface to expose all LIS3LV02DL signals-including SDA/SDI/SDO, SCL/SPC, CS, CK, RDY/INT, VDD_IO, and dual VDD/GND rails-enabling both I²C and SPI communication modes. Power is routed through dedicated decoupling (10 µF tantalum + 100 nF ceramic) directly at the LIS3LV02DL VDD pin.

No active circuitry or level-shifting is present: the adapter preserves native LIS3LV02DL electrical behavior, including 2.7–3.6 V supply range, ±2g/±6g selectable full-scale, and 10-bit digital output resolution. All pins map one-to-one to the IC's 20-pin QFN package via breakout headers.

FAQ

Does STEVAL-MKI009V1 include firmware or require programming?

No. The board is a passive hardware adapter only-it provides physical and electrical access to the LIS3LV02DL sensor but contains no microcontroller, bootloader, or preloaded firmware. Users must implement host-side drivers and data acquisition logic.

What voltage levels does the STEVAL-MKI009V1 support for VDD and VDD_IO?

VDD accepts 2.7–3.6 V DC as specified for the LIS3LV02DL; VDD_IO is internally tied to VDD and supports the same range-no separate IO voltage rail or level translation is provided on this adapter.

Can STEVAL-MKI009V1 be used with Arduino or STM32 Nucleo boards?

Yes-via external wiring from its JP1/JP2 headers to compatible I²C or SPI pins. No onboard level shifters or connectors are included, so users must ensure voltage compatibility and signal routing alignment with their host platform.

Is the LIS3LV02DL on STEVAL-MKI009V1 factory-calibrated?

Yes-the LIS3LV02DL device is factory calibrated for sensitivity and zero-g offset per ST's production test flow. The adapter board itself adds no calibration; raw sensor outputs reflect the IC's calibrated performance within datasheet tolerances.
