What is Microprocessor
Processors usually refer to microprocessors, microcontrollers and digital signal processors. Microprocessors (MPUs) usually represent a powerful CPU, but they are not chips designed for any specific computational purposes that already exist. Such chips are often the core CPUs of personal computers and high-end workstations. The most common microprocessors are Motorola’s 68K series and Intel’s X86 series.

In the electronic component industry, crystal triode and field effect transistor are two kinds of highly respected electronic components. Especially in switching power supply, they are favored by electronic engineers. But how to choose crystal triode and field effect transistor, crystal triode for short, and field effect for the newly introduced purchasing? Like transistors, transistors, which have the characteristics of amplification and switching, are one of the core devices in electronic devices and are widely used. Triode and field effect transistor have the same characteristics and shape, but their working principles are different. Common triode is a current control device, and two-field effect transistor is a voltage control device.

This simple to-construct and-use cell phone hostile to robbery alert is a ultra-straightforward security gadget that appends a security link from a cell phone to an item, hence discouraging the potential burglary of a cell phone in open regions, for example, air terminals, railroad stations, and cafeterias. Since the gliding end of the security link has a standard smaller scale USB connector, you can undoubtedly append it to the USB in a hurry (OTG) port of your cell phone in the wake of circling the security link around a table/seat leg to keep the cell phone set up. At whatever point somebody attempts to withdraw the security link from the cell phone, the cell phone hostile to robbery caution gadget, bolted to a similar leg, alarms you quickly with a thundering cautioning signal!

Many companies’ purchasing will find that when they get the parts in the BOM provided by engineers to purchase materials, suppliers will often ask more carefully, otherwise they will not know what kind of materials to supply you. In serious cases, the purchased materials will not be used. Why is this the case? The problem is that many engineers who are not experienced enough have not completed the model of the device. The following is an example to illustrate what the complete device model is like.

Memory cards are generally characterized by small size, large storage capacity, etc.. They are independent storage media for mobile phones, digital cameras, portable computers, MP3, and other digital products. They are generally card forms, so they are collectively referred to as “memory cards.” Also known as “digital memory card”, “digital memory card”, “storage card” and so on. It is often used as a storage vehicle for our daily life. Let’s take stock of the memory cards we use in our lives and their applications.

The memory cards mainly include MMC cards, SD cards, memory sticks, PCIe flash cards, XQD cards, CF cards, XD image cards, SM cards, and M2 cards. They are described below:
What is silicon controlled rectifiers
Silicon controlled Rectifiers, as known as SCR, a four-layer solidstate current-controlling gadget. The name “silicon controlled rectifier” is General Electric’s exchange name for a sort of thyristor. SCRs are principally utilized in electronic gadgets that require control of high voltage and power. This makes them relevant in medium and high AC control activities, for example, engine control work. A SCR conducts when an entryway heartbeat is connected to it, much the same as a diode. It has four layers of semiconductors that structure two structures to be specific; NPNP or PNPN. Also, it has three intersections marked as J1, J2 and J3 and three terminals(anode, cathode and a door).

TWS dual module for wireless headset
Compared with the traditional Bluetooth headset, the wireless headset uses the latest TWS dual module, which achieves the effect of true wireless stereo, and compared with the traditional Bluetooth headset, not only eliminates the winding of the wire. It also avoids the “stethoscope” effect of headphones during exercise.
