The STEVAL-MKI252KA evaluation kit is based on the IIS3DWBG1, ultrawide bandwidth, low-noise 3-axis digital vibration sensor with extended temperature range.

The evaluation kit includes a square sensing board with the IIS3DWBG1 mounted at the center, connected by flat cable to the STEVAL-MKIGIBV5 adapter board for compatibility with the STEVAL-MKI109D platform. The kit exposes the complete pinout and supports sensor configuration and communication through ST MEMS Studio.

The STEVAL-MKI247A is an adapter board designed to facilitate the evaluation of the 

LSM6DSV80X 6-axis inertial measurement unit (IMU). The board offers an effective solution for fast system prototyping and device evaluation directly within the user’s own application. The STEVAL-MKI247A adapter board exposes the complete LSM6DSV80X pinout in a standard DIL 24 format and supports fast evaluation with the STEVAL-MKI109D platform and MEMS Studio software.

The EVLGANSPIN1-3PH is a three-phase inverter reference design based on GANSPIN611 and an STM32G431RB Arm® Cortex™-M4 MCU at 170MHz, built for sensorless field-oriented control (FOC) of permanent magnet synchronous motors (PMSMs) and brushless dc (BLDC) motors. 

The board includes a 230V ac mains input filter and rectifier, uses a 3-shunt topology, and demonstrates typical power up to 400W at 16kHz with dV/dt tuned to 10V/ns for EMI and motor reliability. It provides UART, Hall sensor, and SWD interfaces and includes 12V, 5V, and 3.3V supply rails generated with VIPER06LS, with shunt amplifiers using TSV911ILT.

The STEVAL-3603BC1 evaluation board demonstrates a synchronous step-down converter design able to deliver up to 3A output current from a 3.3V to 36V input, with a 5V output voltage. The board uses the DCP3603BCMR in the thin SOT23-6L package and shows how efficient conversion can be achieved using the converter, an inductor, two small capacitors, and two resistors. It is suitable for power conversion in major appliances, smart metering, industrial 24V bus conversion, and general-purpose wide Vin power supplies.

The EVLVIPGAN100WP is the STMicroelectronics 100W reference design evaluation board built around the VIPERGAN100WBTR. It implements a complete QR-flyback converter for USB-PD or other isolated 100W supplies with opto-feedback control. The board integrates EMI filtering, surge/overvoltage input protections and optimized thermal layout. Designers can use it to quickly evaluate performance and accelerate design cycles for industrial and telecom power supplies.

The EVLSTGAP3SXS-H is a half-bridge evaluation board designed to evaluate the STGAP3SXS isolated single gate driver for SiC MOSFETs.

The STGAP3SXS offers 10A current capability, rail-to-rail outputs and optimized UVLO and desaturation protection thresholds for SiC MOSFETS. This makes the STGAP3SXS optimal for high-power motor drivers in industrial applications.

The gate driver has a single output pin and a driver line for an external Miller clamp N-channel MOSFET, which optimizes the suppression of positive and negative gate spikes during fast commutations in half-bridge topologies.

The board is supplied by the 5V VAUX connection, which feeds the isolated dc-dc converters for the low-side and high-side driving sections. The gate drivers can be directly supplied by VAUX if a 5V MCU is used, or by the onboard linear regulator if a 3.3V MCU is used. The PWM and Reset inputs can be easily controlled through dedicated connectors while diagnostic outputs are connected to an onboard LED.

Device protection features for desaturation, soft turn-off, and Miller clamp are connected to the recommended network on the board and can be easily evaluated through the board test points.

Dual input pins allow the selection of signal polarity control and implementation of HW interlocking protection to avoid cross-conduction in case of controller malfunction.

The STGAP3SXS allows the implementation of negative gate driving, and the onboard isolated dc-dc converters allow working with optimized driving voltage for SiC MOSFETs.

The EVLSTGAP3SXS-H board allows evaluating all of the STGAP3SXS features while operating with a bus voltage up to 520V. It is possible to increase the bus voltage up to 1200V by replacing the two SiC MOSFETs with appropriate devices in a HiP247-4 package and the C4 capacitance if needed.
