Product details

Overview

STEVAL-MKI123V1 from STMicroelectronics is an adapter board for the LSM330D MEMS inertial module, enabling plug-in evaluation via standard DIL-24 socket. It provides full pin access to both accelerometer and gyroscope interfaces (I²C/SPI), includes on-board decoupling (100nF + 10µF), and is fully compatible with STEVAL-MKI109V2 motherboard for PC-based sensor data acquisition using Unico GUI.

For engineers reviewing the STEVAL-MKI123V1 datasheet, STEVAL-MKI123V1 pinout, STEVAL-MKI123V1 application, or STEVAL-MKI123V1 equivalent, this adapter enables rapid prototyping of motion-sensing systems without custom PCB design-supporting direct interface verification, interrupt behavior testing, and dual-sensor synchronization validation.

Technical Context

The STEVAL-MKI123V1 implements a passive breakout architecture with no active logic or level-shifting circuitry. All LSM330D signals-including dual interrupt outputs (INT1_A/INT2_A, INT1_G/DRDY_G), chip selects (CS_A/CS_G), shared SDA_A/G line, and separate SCL/SCL_A/G-are routed unaltered to 2×12-pin headers matching DIL-24 footprint.

Power domains are segregated: VDD (2.2–3.6 V) supplies core MEMS sensors, while VDD_IO (1.71–3.6 V) powers digital I/O buffers. Two independent ground planes (GND and GND_28) support noise isolation between analog and digital sections per LSM330D layout guidelines.

Key Specifications

Parameter	Value and Actual Design Meaning
Form Factor	DIL-24 socket adapter board - enables direct insertion into standard 24-pin dual-in-line test sockets without soldering.
Supported Device	LSM330D only - mechanical and electrical interface designed exclusively for this 3×5.5 mm LGA-24 inertial module.
Interface Support	Full I²C and SPI access for both accelerometer and gyroscope - includes dedicated CS_A/CS_G, shared SDA_A/G, and separate SCL/SCL_A/G lines.
Power Decoupling	Integrated 100 nF ceramic + 10 µF tantalum capacitors on VDD - meets LSM330D supply noise requirements per ST reference layout.
Interrupt Routing	Four dedicated interrupt pins (INT1_A, INT2_A, INT1_G, DRDY_G/INT2_G) brought out individually - allows independent configuration of motion detection, FIFO threshold, and data-ready events.
Compatibility	Direct plug-in with STEVAL-MKI109V2 motherboard - uses onboard STM32F103 microcontroller as USB-to-sensor bridge for Unico GUI communication.

FAQ

Is STEVAL-MKI123V1 compatible with other LSM330 variants like LSM330DL or LSM330DLC?

No. The STEVAL-MKI123V1 is mechanically and electrically tailored specifically for the LSM330D LGA-24 package. Pin assignments, decoupling network values, and header layout do not match LSM330DL or LSM330DLC, which use different footprints and signal mappings. Using it with non-LSM330D devices may cause misalignment or incorrect signal routing.

Does STEVAL-MKI123V1 include voltage level translation for interfacing with 5 V microcontrollers?

No. The board has no level-shifting circuitry. All digital I/O pins (SDA_A/G, SCL, CS_A, CS_G, INTx) operate at VDD_IO voltage (1.71–3.6 V). Direct connection to 5 V systems requires external bidirectional level translators to avoid damage to the LSM330D's I/O cells.

Can STEVAL-MKI123V1 be used standalone without STEVAL-MKI109V2?

Yes, but only for basic connectivity and signal probing. Without the STEVAL-MKI109V2 motherboard (or equivalent host with proper I²C/SPI drivers), the board lacks firmware, USB interface, and GUI support. Users must provide their own host controller and low-level drivers to communicate with the LSM330D.

What is the purpose of the two separate VDD_IO pins (pins 18 and 22) on the DIL-24 header?

These duplicate VDD_IO connections provide low-impedance power delivery to both accelerometer and gyroscope I/O sections, minimizing crosstalk and ensuring stable logic thresholds during concurrent sensor operation. They reflect the LSM330D's internal separation of digital I/O power domains as specified in its datasheet.
