Product details

Overview

STEVAL-MKI113V1 from STMicroelectronics is an adapter board for the LSM303DLM 3-axis accelerometer and magnetometer MEMS sensor, enabling plug-in evaluation via standard DIL-24 socket. It provides full pinout access, on-board decoupling (10 µF + 4.7 µF + 220 nF + 100 nF), I²C interface support (SCL/SDA for both accel and mag), interrupt outputs (INT1/INT2), and DRDY_M signal for magnetic data ready indication.

For engineers reviewing the STEVAL-MKI113V1 datasheet, STEVAL-MKI113V1 pinout, STEVAL-MKI113V1 application, or STEVAL-MKI113V1 equivalent, this board serves as a hardware bridge between LSM303DLM and STEVAL-MKI109V2 motherboard for rapid sensor prototyping, GUI-based characterization using Unico software, and custom firmware development with direct register-level I²C control.

Technical Context

The STEVAL-MKI113V1 implements passive signal routing without active logic or level shifting - all LSM303DLM pins (including SA0_A, SETP, RESx, DRDY_M) are broken out to dual 12-pin headers (J1/J2) matching DIL-24 footprint. Power is supplied through VDD (2.2–3.6 V) and VDD_IO (1.8–3.6 V) rails, each with dedicated ceramic decoupling.

It interfaces exclusively with the STEVAL-MKI109V2 motherboard's 32-bit STM32 microcontroller bridge, which handles USB-to-I²C translation and hosts Unico GUI firmware. No standalone operation is supported - the board lacks MCU, USB interface, or embedded firmware.

Key Specifications

Parameter	Value and Actual Design Meaning
DIL Socket Type	Standard 24-pin dual in-line, enabling direct insertion into breadboard or carrier sockets for mechanical stability during testing.
Supported Sensor	LSM303DLM only - pinout and layout are fixed to match its 24-pin QFN package mapping (not general-purpose).
Power Decoupling	Four capacitors: 10 µF (bulk), 4.7 µF (mid-frequency), 220 nF & 100 nF (high-frequency bypass) on VDD rail.
I²C Interface	Dedicated SCL/SDA lines for accelerometer (SCL_A/SDA_A) and magnetometer (SCL_M/SDA_M); no arbitration or multiplexing circuitry.
Interrupt Signals	Two open-drain outputs (INT1, INT2) and magnetic data-ready flag (DRDY_M), all routed directly from LSM303DLM pins.
Compatibility	Fully interoperable only with STEVAL-MKI109V2 motherboard - no native USB, UART, or standalone debug capability.

FAQ

Is STEVAL-MKI113V1 a standalone evaluation tool?

No. It requires connection to the STEVAL-MKI109V2 motherboard to function. The board contains no microcontroller, USB interface, or firmware - it is purely a passive breakout adapter for the LSM303DLM sensor, relying entirely on the motherboard for communication, power regulation, and host PC interface.

What voltage levels does STEVAL-MKI113V1 support for VDD and VDD_IO?

VDD accepts 2.2 V to 3.6 V for core sensor operation; VDD_IO supports 1.8 V to 3.6 V for I/O logic. These rails are externally supplied via the STEVAL-MKI109V2 motherboard - the adapter board itself has no voltage regulation or level-shifting circuitry.

Can STEVAL-MKI113V1 be used with sensors other than LSM303DLM?

No. Its PCB layout, pinout mapping, and decoupling network are specifically designed for the LSM303DLM's 24-pin QFN package and electrical characteristics. Pin assignments (e.g., SETP, RES1–RES4, DRDY_M) do not align with other ST MEMS devices like LSM303DLHC or LIS3MDL.

Does STEVAL-MKI113V1 include ESD protection or filtering on I²C lines?

No. The board provides direct pin-to-header routing for SCL/SDA signals without series resistors, ferrite beads, or TVS diodes. System-level ESD protection must be implemented externally - typical practice when connecting to the STEVAL-MKI109V2 motherboard, which includes I²C bus conditioning.
