Product details
Overview
STEVAL-MKI105V1 from STMicroelectronics is an adapter board for the LIS3DH 3-axis digital accelerometer, designed to plug directly into a standard DIL-24 socket and provide full pin access for rapid prototyping and sensor evaluation. It includes on-board decoupling (100 nF + 10 µF) on VDD, supports I²C/SPI interfaces via SDA/SCL/SDO/CS, and delivers interrupt outputs (INT1/INT2) and analog inputs (ADC1–ADC3).
For engineers reviewing the STEVAL-MKI105V1 datasheet, STEVAL-MKI105V1 pinout, STEVAL-MKI105V1 application, or STEVAL-MKI105V1 equivalent, this board enables immediate integration with STEVAL-MKI109V2/V3 motherboards, Unico GUI software, and custom firmware development targeting motion-sensing applications in wearables, IoT nodes, and industrial diagnostics.
Technical Context
The STEVAL-MKI105V1 serves as a passive mechanical and electrical interface between the LIS3DH MEMS accelerometer and host evaluation platforms. It maps all 16 functional pins of the LIS3DH-including power (VDD, VDD_IO), digital interfaces (I²C: SDA/SCL; SPI: SDO/SDO/CS), interrupts (INT1/INT2), and analog auxiliary inputs (ADC1–ADC3)-to a 24-pin DIL footprint with unpopulated jumpers (JP1/JP2) for signal routing flexibility.
No active components or microcontroller are present: the board relies entirely on external host control (e.g., STM32-based STEVAL-MKI109V2/V3) for configuration, data acquisition, and real-time visualization via Unico GUI. All passives are pre-mounted except three 0 Ω resistors (R1–R3) used for optional signal path selection.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| DIL Socket Type | Standard 24-pin dual in-line, enabling plug-and-play insertion into breadboard or motherboard sockets without soldering. |
| LIS3DH Pin Coverage | Full 16-pin mapping including VDD, VDD_IO, GND, SDA, SCL, SDO, CS, INT1, INT2, ADC1–ADC3 - no pin multiplexing or omission. |
| Power Decoupling | 100 nF ceramic + 10 µF tantalum capacitors on VDD line - meets LIS3DH recommended supply filtering for stable 2.4–3.6 V operation. |
| Interface Support | I²C (SDA/SCL) and SPI (SDO/CS) protocols supported simultaneously - allows host firmware to select communication mode without hardware change. |
| Interrupt Outputs | Dedicated INT1 and INT2 pins routed to DIL pins 10 and 9 - enables configurable motion detection, FIFO threshold, or data-ready signaling per LIS3DH register settings. |
| Analog Inputs | Three ADC input pins (ADC1–ADC3) exposed - permits connection of external analog sensors (e.g., temperature, light) for synchronized sampling with accelerometer data. |

FAQ
Does STEVAL-MKI105V1 include the LIS3DH sensor?
No. The board is an adapter only and does not contain the LIS3DH IC. Users must supply their own LIS3DH device and mount it onto the DIL-24 socket. The board provides all necessary signal routing, power conditioning, and pin breakout - but no active silicon.
Which motherboards is STEVAL-MKI105V1 compatible with?
It is fully compatible with STEVAL-MKI109V2 and STEVAL-MKI109V3 motherboards, both featuring STM32F401RE or STM32F407VG microcontrollers. These boards provide USB-to-UART bridging, sensor register access, and Unico GUI communication - no additional drivers or firmware required.
Can STEVAL-MKI105V1 be used standalone without a motherboard?
No. It has no onboard microcontroller, power regulation, or USB interface. It requires connection to a compatible motherboard (e.g., STEVAL-MKI109V2/V3) or custom host system that supplies regulated 2.4–3.6 V, I²C/SPI signals, and interrupt handling logic.
What software tools support STEVAL-MKI105V1?
ST's Unico GUI is the primary tool - a free Windows application that auto-detects the LIS3DH via the motherboard, enables real-time data streaming, register configuration, interrupt setup, and FFT analysis. Custom firmware using ST's X-CUBE-MEMS1 middleware is also supported.
