STMicroelectronics STEVAL-MKI013V1

Overview

STEVAL-MKI013V1 from STMicroelectronics is a DIL-24 socket-compatible adapter board designed to evaluate the LIS302DL 3-axis digital accelerometer. It provides full pin access, on-board decoupling (10 µF + 100 nF), and direct plug-in compatibility with the STEVAL-MKI109V2 motherboard for PC-based sensor evaluation using Unico GUI.

For engineers reviewing the STEVAL-MKI013V1 datasheet, STEVAL-MKI013V1 pinout, STEVAL-MKI013V1 application, or STEVAL-MKI013V1 equivalent, this board enables rapid prototyping of motion-sensing interfaces in embedded systems where compact mechanical integration and I²C/SPI signal routing validation are critical.

Technical Context

The board implements a passive breakout interface between the LIS302DL's 16-pin LGA package and a standard 24-pin dual-in-line socket. All LIS302DL signals-including SCL, SDA, SDO, CS, INT1, INT2, VDD, and multiple GND pins-are routed to corresponding DIL-24 header positions without level shifting or buffering.

It supports both I²C and SPI communication modes via configurable jumpers (JP1, JP2) and includes dedicated power filtering for Vdd_IO and VDD rails. No microcontroller or firmware is onboard-the board relies entirely on host-side control through the STEVAL-MKI109V2 bridge platform.

FAQ

Does STEVAL-MKI013V1 include an onboard microcontroller?

No. The board contains no active processing element. It is a passive adapter that routes LIS302DL signals to a DIL-24 socket and requires connection to the STEVAL-MKI109V2 motherboard-or equivalent host controller-for communication and data acquisition.

Can STEVAL-MKI013V1 be used independently without STEVAL-MKI109V2?

No. It lacks USB interface, firmware, or signal conditioning circuitry. Standalone use is not supported-operation requires the STEVAL-MKI109V2's 32-bit microcontroller bridge to translate sensor data to PC via USB and run Unico GUI or custom software.

What is the purpose of JP1 and JP2 jumpers on the board?

JP1 selects between I²C and SPI communication mode; JP2 configures SDO pin functionality (data output or 3rd interrupt). These jumpers define the LIS302DL interface protocol and interrupt behavior before connecting to the host motherboard.

Is the LIS302DL soldered to the STEVAL-MKI013V1 board?

No. The LIS302DL is not mounted. The board provides a socket-compatible footprint and signal breakout-users must source and install the LIS302DL IC separately onto the adapter or integrate it elsewhere in their system under test.
