Product details
Overview
STEVAL-MKI090V1 from STMicroelectronics is an adapter board designed to interface the LIS331DLF 3-axis digital accelerometer (SPI/I²C) into standard DIL-24 sockets for rapid prototyping and evaluation. It provides full pinout mapping, integrated VDD decoupling capacitors, RoHS compliance, and mechanical compatibility with ST's family of MEMS adapter boards.
For engineers reviewing the STEVAL-MKI090V1 datasheet, STEVAL-MKI090V1 pinout, STEVAL-MKI090V1 application, or STEVAL-MKI090V1 equivalent, this board enables plug-and-play sensor evaluation without custom PCB design-ideal for early-stage motion sensing validation in industrial, consumer, and IoT edge nodes.
Technical Context
The board implements a passive breakout architecture with no active components: all LIS331DLF signals-including VDD (2.16–3.6 V), GND, SCL/SDA or SPC/SDO, INT1/INT2, and CS-are routed 1:1 to the DIL-24 footprint. No level-shifting, voltage regulation, or signal conditioning circuitry is included.
Designed exclusively for evaluation use, it lacks onboard microcontroller, firmware, or USB interface-requiring external host (e.g., STM32 Nucleo or Arduino via I²C/SPI) to drive the LIS331DLF and read acceleration data at up to 1 kHz output data rate.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Form Factor | DIL-24 socket adapter board - enables direct insertion into breadboard-compatible or custom carrier sockets without soldering. |
| Target Device | LIS331DLF 3-axis ±2g/±8g digital accelerometer - supports both I²C and SPI interfaces with programmable full-scale ranges. |
| Power Supply | VDD only (2.16–3.6 V); no onboard regulator - requires clean external supply connected via DIL-24 power pins. |
| Decoupling | Integrated 100 nF ceramic capacitor on VDD line - meets LIS331DLF noise immunity requirements per datasheet. |
| Compliance | RoHS-compliant PCB and assembly - satisfies EU Directive 2011/65/EU for hazardous substance restrictions. |
| Mechanical Compatibility | Pinout-matched with ST's MKI-series adapter boards - allows seamless swapping between LIS331DLF, LIS302DL, and LIS344ALH evaluation setups. |

FAQ
Does STEVAL-MKI090V1 include firmware or drivers?
No. The board contains only passive routing and decoupling components. Users must provide host-side firmware (e.g., STM32 HAL or Arduino Wire/SPI libraries) to configure the LIS331DLF and read acceleration registers. ST provides example code separately via AN3308 and UM0752 application notes.
Can STEVAL-MKI090V1 be used with 5 V microcontrollers?
No. The LIS331DLF operates strictly at 2.16–3.6 V and is not 5 V tolerant. Direct connection to 5 V I/O hosts will damage the sensor. Level-shifting circuitry must be added externally if interfacing with 5 V systems.
Is STEVAL-MKI090V1 still in production?
No. STMicroelectronics has marked STEVAL-MKI090V1 as obsolete (as noted in Doc ID 17453 Rev 1). Aetrix Electronics maintains limited legacy stock for design continuity; no new manufacturing is planned. Replacement options include STEVAL-MKI182V1 (for LIS2DH12) with updated DIL-24 pinout compatibility.
What are the exact dimensions and mounting hole specifications?
The board measures 25.4 mm × 15.2 mm (1.0" × 0.6") with two 3.2 mm diameter non-plated mounting holes centered 20.3 mm apart along the long axis. No standoffs or screws are included; mechanical drawings are provided in the schematic appendix of Doc ID 17453.
