Product details
Overview
STEVAL-MKI174V1 from STMicroelectronics is a DIL24 socket adapter board for the LIS2DS12 ultra-low-power 3-axis accelerometer, providing full pin access, on-board decoupling (10 µF + 100 nF per supply rail), and level-shifting support for VDDIO_1V8 and VDD_1V8 domains. It enables rapid evaluation and integration into user systems requiring motion sensing with <1.5 µA typical standby current and ±2g/±4g/±8g/±16g dynamic ranges.
For engineers reviewing the STEVAL-MKI174V1 datasheet, STEVAL-MKI174V1 pinout, STEVAL-MKI174V1 application, or STEVAL-MKI174V1 equivalent, this adapter board supports direct plug-in to standard DIL24 sockets, interoperability with the STEVAL-MKI109V3 motherboard, and seamless interface to Unico GUI via I²C (SCL/SDA) or SPI (CS/SCL/SDA/SDO) protocols under dual-voltage operation.
Technical Context
The board implements bidirectional voltage translation using the LDS3985M18R level shifter and ST2378E buffer to isolate and adapt LIS2DS12's 1.8 V I/O domain (VDDIO_1V8, INT1_1V8, INT2_1V8, SCL_1V8, SDA_1V8) from host system logic levels. All critical power rails-VDD (1.71–3.6 V), VDDIO (1.71–3.6 V), and VDDIO_1V8 (1.8 V)-are independently decoupled with ceramic capacitors.
It routes all 24 pins of the LIS2DS12 in a standard DIL24 footprint, including dual interrupt outputs (INT1_XL, INT2_XL), programmable digital output (SDO/SA0), chip select (CS), serial clock (SCL/SPC), and serial data (SDA/SDI), enabling both I²C and SPI communication modes without soldering or wiring modifications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| DIL24 Socket Compatibility | Fully compliant with industry-standard 24-pin dual in-line package socket footprint for mechanical and electrical insertion. |
| LIS2DS12 Pin Access | 100% pinout exposed-including SDO/SA0, CS, SCL/SPC, SDA/SDI, INT1_XL, INT2_XL, RES, and all GND/VDD terminals. |
| Power Decoupling | Integrated 10 µF bulk + 100 nF high-frequency ceramic capacitors on VDD and VDDIO rails for stable low-noise sensor operation. |
| Voltage Translation | LDS3985M18R and ST2378E enable reliable 1.8 V I/O signaling (INTx, SCL, SDA, SDO) interfaced to 3.3 V or 5 V host systems. |
| Interface Support | Native I²C (400 kHz fast-mode) and SPI (up to 10 MHz) protocol readiness via jumper-configurable signal routing. |

FAQ
Does STEVAL-MKI174V1 require external power or firmware to operate?
No. The board draws power from the host motherboard (e.g., STEVAL-MKI109V3) via its DIL24 socket interface. It contains no active firmware or microcontroller-only passive components and level shifters. Operation begins immediately upon connection to a compatible host with appropriate driver or GUI software installed.
Can STEVAL-MKI174V1 be used standalone without STEVAL-MKI109V3?
Yes, but only with an external host that provides DIL24-compatible power (VDD, VDDIO), I²C/SPI signals, and proper voltage-level matching. The board lacks onboard regulation or USB interface; it is designed as an adapter-not a self-contained evaluation kit-and relies on external signal sourcing and control logic.
What is the purpose of jumpers SB1–SB12 on the board?
These solder bridges configure signal routing and voltage domain selection-for example, enabling/disabling level shifters (U2/U3), selecting VDDIO source (internal vs. external), or connecting INT1/INT2 to host GPIOs. Their default configuration matches STEVAL-MKI109V3 compatibility; modification allows custom host interfacing per schematic Figure 1.
Is the LIS2DS12 IC pre-soldered on STEVAL-MKI174V1?
No. The board is an empty adapter-no LIS2DS12 is mounted. Users must supply their own LIS2DS12 in a compatible 12-lead LGA package and solder it onto U1 footprint, or use a socketed carrier. The design assumes user-provided device placement for flexibility across sampling, qualification, and production evaluation stages.
