The STEVAL-TTM005A is a powerful tool that has been specifically designed for developing and testing automotive motor control applications. The board ensures accurate motion sensing based on rotor position estimation with resolver feedback. This rotor position estimation allows to obtain an excellent control since zero speed, with the most advanced F.O.C. algorithms reducing any torque and speed ripple on the motor. The board is supplied by a 12 V dc input and 5 V and includes ST’s latest high-precision, low-noise operational amplifiers and an optimized excitation circuit that guarantees a reliable and accurate operation. The excitation signal, generated by an external compatible control board (STEVAL-TTM004V1, STEVAL-TTM002V1, or the STM32G474RE connected with the Arduino connectors) is amplified by the TSB582 able to excite the resolver coil. The two phase shifted resolver outputs, for sine and cosine waves, are treated by a TSB514 op amp and then converted into digital signals by the microcontroller on the control board. With its high accuracy and extended compatibility, the board is an essential tool for validating and testing any high precision system for motion control sensing with high performance thanks to the rotary resolver and a best-in-class signal conditioning circuitry.

The compact USB Type-C to DisplayPort adapter reference design, with USB Type-C connector and DisplayPort connector, exploits Alternate Mode of the USB Type-C and Power Delivery specifications to offer a comprehensive VESA®DisplayPort Standard interface. With this adapter, you can connect a monitor with a DisplayPort interface to any laptop, tablet or smartphone with a reversible USB Type-C connector that is compliant with the Power Delivery specification. The DisplayPort Alternate Mode allows video data to be delivered through the SuperSpeed USB lines on the Type-C connector, while Auxiliary lanes (AUX) and hot plug detection (HPD) signals are sent through other Type-C lines. The high-performance ARM®Cortex®-M0 32-bit STM32F072 microcontroller engages in DisplayPort Alt Mode negotiation through vendor-defined messages (VDM) according to the USB Power Delivery Specification. The messages are transmitted along configuration channel (CC), through a simple discrete analog front end (AFE) interface between the STM32 MCU and the USB Type-C connector. The STM32 microcontroller running the ST USB Middleware stack and the embedded USB 2.0 controller provide the Billboard Device Class support as required by the USB Power Delivery standard, as well as the Device Firmware Upgrade capability.

STEVAL-WESU1 is a reference design developed and optimized to help designers implement the latest technologies in wearable and portable applications. The small form factor of the hardware allows it to be enclosed in a watch strap, so the user can experience a real activity monitoring system and immediately begin appreciating the sensor data acquisition, as well as all of the embedded hardware and firmware features, also thanks to the ST WeSU app available free of charge from Apple Store™ and Google Play™ stores. The Apps are based on BlueST SDK, available on GitHub. Advanced users can also further reduce the hardware form factor; please refer to STEVAL-WESU1 user manual for more details. The STEVAL-WESU1 firmware package is built on the STM32Cube software technology so it can easily be augmented with further algorithms. It runs on STM32L151VEY6 and includes the drivers to manage three sensors (LSM6DS3, LIS3MDL and LPS25HB), the Bluetooth low energy network processor (BlueNRG-MS) and the battery management ICs (STC3115 and STNS01).

The STEVAL-XPLM01CPL is a simple yet very useful tool for power line communication testing on AC power networks. It includes simple two-wire connectivity to any PLC transmitter/receiver and a standard connector for an AC power cord (2-pin AC plug, 8-shape female end). The main components to achieve suitable signal coupling are: - PLC 1:1 transformer for differential coupling and basic electrical isolation - SM6T15CA 600 W Transil +320 V ac varistor for effective protection against ESD, EFT and surge disturbances from the power line - High voltage AC blocking capacitor with X2 safety class - Tuning series inductor to adjust the frequency response The STEVAL-XPLM01CPL can be very easily interfaced with the X-NUCLEO-PLM01A1 to test PLC communication performance over an AC mains network. The frequency response of the coupling circuit is wide enough to fit any narrow-band PLC signal under normal test conditions. However, it can be easily adjusted by changing only the tuning series inductor L1. The STEVAL-XPLM01CPL is suitable for lab measurements using equipment like an isolated probe for an oscilloscope or a spectrum analyzer, or to inject a signal from an arbitrary function generator.
