-
- The role of vga interface
- The VGA interface (Video Graphics Array) is an analog video interface that connects the computer graphics card and the monitor to transmit video signals, including RGB color signals and synchronization signals. The VGA interface has high compatibility and is easy to use, but its transmission of analog signals will cause a decrease in image quality, and the highest resolution only supports 1920×1200, and the cable volume is also large.

-
- Is the vga interface the same as the hdmi interface?
- No, the VGA connector and the HDMI connector are different. Technical differences lie in signal type, resolution, refresh rate and audio transmission; connector differences lie in shape, size and locking mechanism; application scenario differences lie in device type, resolution and audio requirements.

-
- What does brushless motor mean and what is it used for?
- A brushless motor is a DC motor that uses electronic commutation technology instead of brushes. Its advantages include: maintenance-free, long service life, high efficiency, low noise, small size, and brushless motors are widely used in power tools, home appliances, automobiles, industrial equipment, and aerospace fields.
- Common Problem 928 2024-04-25 16:15:24
-
- The difference between brushless motors and brushed motors
- The main differences between brushless and brushed motors: Design: Brushless motors use electronic commutation, while brushed motors use carbon brushes and commutators. Working principle: Brushless motors control current through sensors and electronic commutation, while brushed motors change the direction of current through contact between carbon brushes and commutator. Advantages: Brushless motors offer higher efficiency, longer life, lower maintenance requirements and less electromagnetic interference.

-
- The function of intermediate relay
- The intermediate relay has the functions of amplification, isolation and protection in the control circuit, including: amplifying weak signals to control larger current loads; providing electrical isolation to prevent control signals and loads from interfering with each other; protecting loads from overcurrent, overvoltage or Short circuit damage.
- Common Problem 1089 2024-04-25 16:09:14
-
- What are the control methods of stepper motors?
- The main control methods of stepper motors include: full step control: each pulse corresponds to a step angle, and the rotation is smooth but slow. Half-step control: Each pulse corresponds to half the step angle, and the rotation speed is fast but the accuracy is low. Micro-stepping control: subdivide the step angle to achieve higher accuracy and speed. Current control: Control current to adjust torque and speed to achieve smooth rotation and quick response. PID Control: Feedback control to improve stability and accuracy for complex and highly dynamic applications. Vector Control: Optimizes motor performance for higher torque, speed and efficiency for high performance and reliability applications.
- Common Problem 501 2024-04-25 16:03:17
-
- The difference between stepper motor and servo motor
- The main difference between stepper motors and servo motors is: Working principle: Stepper motors rotate through pulses, while servo motors rotate precisely through feedback control. Control mode: stepper motors rely on pulse signals, and servo motors rely on closed-loop control. Features: Servo motors have high precision, large torque, and smooth speed. Stepper motors have limited step accuracy, low torque, slow speed, and obvious vibration noise.

-
- The role of temperature sensor
- The function of a temperature sensor is to convert temperature changes into electrical signals that can be processed by electronic systems. Its working principle is based on resistance changes, voltage generation or resonant frequency changes. Major types include thermistors, thermocouples, piezoelectric sensors, infrared sensors, and fiber optic sensors. They are widely used in industrial, consumer electronics, medical, environmental monitoring and automotive fields. When selecting a temperature sensor, consider temperature range, accuracy, response time, size, cost, and environmental compatibility.
- Common Problem 435 2024-04-25 15:51:17
-
- How the temperature sensor works
- Temperature sensors use various principles to measure temperature and convert it into an electrical signal. How they work includes: Thermocouples utilize the thermal electromotive force between dissimilar metals; RTDs measure resistance as a function of temperature; NTC/PTC thermistors change semiconductor resistance; Temperature diodes have a forward bias voltage proportional to temperature; Infrared sensors detect Infrared radiation from a target object; silicon sensors convert temperature using analog or digital technology.
- Common Problem 962 2024-04-25 15:48:15
-
- What types of temperature sensors are there?
- There are many types of temperature sensors including: thermocouple, RTD, semiconductor, infrared, laser, bimetal, liquid expansion, and fiber optic sensors. Factors such as measurement accuracy, temperature range, response time, durability, environmental conditions, cost, and availability should be considered when selecting.
- Common Problem 1013 2024-04-25 15:45:24
-
- What are electronic components
- Electronic components are the basic building blocks of circuits and electronic devices that control, regulate, or amplify electronic signals. They include: Resistors: Limit current. Capacitors: Store charge. Diodes: One-way current conductors. Transistors: Amplify or switch signals. Integrated circuits: Contain hundreds of Thousand-element chip transformer: transfers voltage or current Inductor: stores magnetic energy
- Common Problem 548 2024-04-25 15:42:15
-
- What are the commonly used electronic components?
- Commonly used electronic components include: Passive components: resistors, capacitors, inductors Active components: diodes, transistors, transistors, IC Other components: connectors, switches, fuses, relays, sensors
- Common Problem 1114 2024-04-25 15:36:13
-
- Is fpga an embedded development?
- Yes, FPGA (Field Programmable Gate Array) is a type of embedded development. FPGAs are programmable and customizable, making them suitable for a variety of embedded systems, including real-time control, data acquisition, and wireless communications. Advantages include customizability, parallel processing, low power consumption and reliability.
- Common Problem 864 2024-04-25 15:33:12
-
- Is FPGA hardware or software?
- FPGA is essentially hardware that contains programmable logic blocks and configurable interconnects that are programmed to perform specific functions by loading configuration information. Unlike software, the configuration of an FPGA can only be modified during programming, and the logic is executed in hardware, orders of magnitude faster than software.
