The STM32U083C-DK Discovery kit from STMicroelectronics is a complete demonstration and development platform for the STM32U083MCT6 microcontroller. It may be used as a reference design for application development before porting to the final product.
The full range of hardware features on the board helps the designer to evaluate all the MCU’s peripherals including the USB 2.0 interface, segment LCD controller, capacitive touch-sensing channels, and temperature sensor.
ARDUINO Uno V3, mikroBUS™ and extension connectors provide for easy connection to extension shields or application-specific daughterboards.
The STM32U083C-DK Discovery kit does not require any separate probe as it has an integrated STLINK-V2EC debugger/programmer. The kit is operated by plugging it into a PC through a standard USB Type-A or USB Type-C®-to-USB Type-C cable.
The board is supported by the STM32CubeU0 embedded software package.

The EVSPIN32G06Q1S1 board from STMicroelectronics is a complete three-phase inverter based on the STSPIN32G0601 controller, which integrates a three‑phase 600 V gate driver and an Arm® Cortex®-M0+ microcontroller. It is suitable for loads up to around 250 W, and drawing a 1 Arms phase current.
The power stage features STGD6M65DF2 IGBTs, but can be populated with any IGBT or power MOSFET in a DPAK or powerFLAT 8×8 HV package. The board has a single-shunt sensing topology, and supports both field-oriented control and six‑step control algorithms in either sensored or sensorless mode. This means that the board can drive permanent magnet synchronous motors (PMSMs) and brushless dc (BLDC) motors.
The evaluation board is compatible with a wide input-voltage range from 35 V ac/50 V dc to 280 V ac/400 V dc. It includes a power-supply stage based on the VIPER06XS offline power converter in flyback configuration to generate the +15 V and +3.3 V supply voltage required by the application.
Other features are:
- Over-current threshold set to 2.8 A peak
- Smart shutdown over-current protection
- Digital Hall sensors and encoder input
- Bus-voltage sensing
- External connection through STLINK-V3SET
- Buttons and trimmer for user interfacing

The EVLPWD-FAN-PUMP evaluation board for the PWD5T60 motor driver power stage from STMicroelectronics supports flexible, ready-to-use control methods, and so helps to accelerate the development of reliable, compact and efficient fans and pumps.
The EVLPWD-FAN-PUMP board features the PWD5T60 and an STM32G0 microcontroller based on an Arm® Cortex®-M0+ core, enabling field-oriented control (FOC) or six-step control of permanent magnet synchronous motors (PMSM) and brushless dc (BLDC) motors. The board offers a choice of single- or triple-shunt current sensing. Because the PWD5T60 is highly integrated, it has enabled STMicroelectronics to implement the board’s motor power stage in a small circular form factor, making it ideal for use in fans and pumps. It also includes a power-supply circuit which provides 12 V and 3.3 V supply voltages for the application, with a complete ac line filter at the input stage.
The EVLPWD-FAN-PUMP includes built-in bus-voltage detection to help to take advantage of the safety design of the PWD5T60, which provides over- and under-voltage lockout protection for each bootstrap circuit to prevent unsafe or inefficient operation.
The PWD5T60 is also robust, and features shoot-through protection with interlock and preset default dead time, providing fail-safe protection against shoot-through currents. Additionally, the PWD5T60 withstands voltage drops below ground.
The board is ready to use and runs the FOC and 6-step control firmware included in the X-CUBE-MCSDK motor control software development kit, which is available free of charge from the ST website.
The NCD57252 evaluation driver board enables evaluation of the NCD57252, a high-current gate driver which can directly drive two independent IGBTs in any configuration. The driver provides 5 kVrmss of internal galvanic isolation from input to each output and functional isolation between the two output channels.
The board can be externally connected to a power device to verify the real behavior of the NCD57252 in the system. It contains all the necessary peripheral components for direct connection to the power device.
The input bias is configured so that the power rails can be powered by many types of integrated dc-dc power supplies, or powered directly from an external power source. The PCB design is optimized to reduce loop areas and provide clear and simple measurement of all signals.
All the parts except optional dc-dc power sources are top-mounted, which allows for easy replacement. The board can serve as a reference design for future use.
