Product details

Overview

STEVAL-MKI014V1 from STMicroelectronics is a MEMS 3-axis analog-output demonstration board built around the LIS344ALH low-power capacitive accelerometer, supporting ±2g/±6g full-scale ranges, normal or power-down operation modes, and self-test functionality via jumper configuration. It delivers direct and buffered analog outputs for X/Y/Z axes and integrates a linear voltage regulator plus rail-to-rail low-noise quad op-amp configured as non-inverting buffers.

For engineers reviewing the STEVAL-MKI014V1 datasheet, STEVAL-MKI014V1 pinout, STEVAL-MKI014V1 application, or STEVAL-MKI014V1 equivalent, this board enables rapid evaluation of LIS344ALH sensor performance in motion-sensing systems requiring analog interface validation, scale selection, and power-state control without custom PCB design.

Technical Context

The board implements a complete signal chain for the LIS344ALH: raw sensor outputs are accessible at test points, while buffered versions pass through a rail-to-rail, low-noise quad operational amplifier (configured as unity-gain non-inverting buffers) to drive higher-impedance loads with minimal distortion. Power conditioning is handled by an integrated linear voltage regulator supplying stable VDD to the MEMS IC.

Jumper-based configuration allows hardware-selectable full-scale range (2g or 6g), power-down activation, and self-test initiation-eliminating need for external microcontroller GPIO control during basic functional verification. All control signals (FS, PD, ST) are routed to headers for optional external logic interfacing.

Key Specifications

Manufacturer

STMicroelectronics is a global semiconductor leader headquartered in Geneva, designing and manufacturing microcontrollers, sensors, power ICs, and analog/mixed-signal devices for industrial, automotive, and consumer applications.

This board belongs to ST's STEVAL (ST Evaluation) series, purpose-built to accelerate hands-on evaluation of ST's MEMS sensors-specifically enabling analog-domain characterization, scale selection, and self-test verification without firmware development.

FAQ

What power supply voltage does STEVAL-MKI014V1 require?

The board accepts a single 3.3 V to 5.5 V DC input, regulated internally by an integrated linear voltage regulator to supply the LIS344ALH sensor at its nominal VDD. No external voltage translation or sequencing is needed-direct connection to a lab bench supply or USB-powered adapter suffices for operation.

How do I switch between ±2g and ±6g full-scale ranges?

Full-scale selection is performed using three solder-jumpers (J1, J2, J3) labeled FS1–FS3 on the board. The specific jumper configuration (open/closed) determines the selected range per the LIS344ALH datasheet truth table. No software or external logic is required-hardware setting takes effect immediately on power-up.

Can I access both raw and buffered sensor outputs simultaneously?

Yes. Test points labeled "SENSOR_OUT_X/Y/Z" provide unbuffered analog outputs directly from the LIS344ALH pins. Adjacent headers labeled "BUFFERED_OUT_X/Y/Z" deliver the same signals after amplification by the rail-to-rail low-noise op-amp stage, enabling comparison of signal integrity under different load conditions.

Is STEVAL-MKI014V1 still recommended for new designs?

No-STMicroelectronics has marked STEVAL-MKI014V1 as obsolete (per Doc ID 18042 Rev 1, October 2010). While functional for legacy evaluation, new designs should consider ST's current-generation evaluation platforms such as STEVAL-MKI197V1 (for LIS2DH12) or STEVAL-MKI208V1K (for LSM6DSOX), which support updated interfaces and extended features.
