This evaluation board aims to help you test and develop motor control designs for applications such as power tools, household appliances, fans, and water pumps through a flexible evaluation platform, and even switch between external sensor and sensorless position feedback data methods.

2. Fully integrated embedded motor controller with expandable memory for automobiles!
TDK has expanded its micronas embedded motor controller product line with HVC 4420F, which features extended flash memory for driving small brushed, stepper, or brushless motors. It aims to meet the latest demands of the automotive industry to provide newly introduced diagnostic functions in the field of intelligent actuators. By expanding flash memory to 64 KB and SRAM to 4 KB, HVC 4420F can meet the growing functional and diagnostic needs of OEMs. Currently, OEMs use their own ideas and methods in diagnosis. This includes sensor data fusion strategies, actuator states, and generated activities. To ensure the necessary data analysis, software routines must be executed that can activate basic hardware diagnostic functions while respecting OEM frameworks to ensure proper integration. Due to its larger memory and built-in diagnostic feature set, HVC 4420F provides storage capacity and processing power to perform these operations, which is unique in the environment of intelligent actuators.

4. Smart Home - Robot Nanny Design Solution!
Based on STM32, the robot nanny system consists of several modules, including a wheeled robot, XBee coordinator, RFID smart floor, and upper computer. The wheeled robot consists of a motherboard, sensor module, RF module, servo module, power module, and robot metal body. The sensor module includes an electronic compass, infrared sensor, and RFID card reader. The motherboard is developed with the ARM Cortex-M3 core microprocessor STM32F103VCT6 as the core, which collects sensor module data information and realizes communication connection between the robot and XBee coordinator. The system can stably and efficiently complete the set tasks through autonomous decision-making in a simulated smart home environment, which can meet the application requirements of robot nannies.

5. ST: Empower the Internet of Things with cloud intelligence capabilities!!
STMicroelectronics' X-CUBE-AVS software package enables Amazon's Alexa Voice Service (AVS) to run on STM32 * microcontrollers, enabling advanced conversational user interfaces with cloud intelligence capabilities (automatic speech recognition and natural language understanding) to appear on simple IoT devices such as smart home appliances, home automation devices, and office equipment.

How to connect the TMC2130 stepper motor driver to the Arduino UNO for control!
Some wiring of TMC2130- a more basic version of the driver, but without SPI interface. The TMC2100 version does not require a connection to be established between the microcontroller and the CS pin (chip selection), and when applying this diagram, the first thing to check in the data table is the absolute maximum rated value, which should not be exceeded. It seems that the STEP and DIR ports can be driven by a microprocessor, and the motor can be controlled in this way (and also through the SPI bus)

7. Use compact industrial robots to improve productivity!
This article focuses on what factors prevent robots from being deployed on a larger scale like colleague robots, and why there have been changes. Then, an example robot in the form of a robotic arm from KUKA Robotics Corp. was introduced, and how it can be applied to both large and small facilities was demonstrated.

8. Use BridgeSwitch current sensing signal output in field oriented control of brushless DC motors!
High performance motor drives typically use field oriented control because it can provide smooth and efficient operation across the entire speed range. BridgeSwitch provides unique functionality by offering small signal output (instantaneous representation of positive phase current).

9. From laser to workbench: New technology accelerates the production of PCB solder mask
Limata has announced a new technology that they claim greatly improves the production efficiency of solder mask layers at a lower manufacturer cost. This technology, known as LUVIR, solves the above problems by combining UV and IR laser power. This technology involves using IR light to heat the ink immediately before the UV laser begins to cure it. The increase in heat makes the solder mask more reactive to ultraviolet radiation, greatly reducing the ultraviolet power required to cure the solder mask.

10. PCB space restrictions? How can intermediate bus converters provide assistance!
The intermediate bus architecture is an emerging method used by power designers to save PCB space. This article discusses the benefits and trade-offs of solutions using this technology, as well as how to extend it to meet application specific requirements. The field of power electronics has become a mature and highly researched industry, with a history dating back over 100 years. Peter Cooper Hewitt invented the mercury arc rectifier in 1902. The inventions of these rectifiers were followed by the hot cathode gas tube rectifier in 1926, the transistor in 1948, the p-n-p-n silicon transistor in 1956, and the IGBT in 1980. In the 21st century, power electronics continue to develop in the fields of clean energy, electric vehicles, and server applications. The growth of these emerging industries requires power designers to find new innovative solutions to meet constantly evolving needs, thus requiring smaller and more cost-effective solutions.
