Today to share the wireless charging type rx and tx knowledge, which will also explain the wireless charging program ranking, if you happen to solve the problem you are now facing, don't forget to pay attention to the site, now start!
< ul>White line: negative voltage Data line (marked with: Data- or USB Port -) Green line: positive voltage data line (marked with: Data or USB Port) Black line: ground (marked with: GND). The general arrangement order is VCC, D-, D, GND, the arrangement is fixed, but there are two directions, the wrong connection of the data line can not identify the usb device at most, the power line must not be connected wrong, it is recommended that you read the motherboard manual or use a multimeter test.
Mobile phone motherboard signal pin welding is a mobile phoneA very important step in maintenance. First, the function and position of each pin must be understood to ensure proper connection. Secondly, before welding, make sure that the pin and welding pad have enough spacing to avoid short circuit. Finally, it is necessary to weld at the appropriate temperature and time to ensure the quality of welding. Only by correctly welding the signal pin, the mobile phone motherboard can work normally.
The four wires inside the mobile phone charging cable are: Red line: positive power terminal (marked with: +5V or VCC). White line: Negative voltage Data line (identified as: Data- or USBPort-). Green line: positiveMedium is in pairs, sending and receiving is 1 pair. Sending and receiving must be at the same time, only receiving and not sending, only sending and not receiving are problematic.
rx indicates that rx indicates receive and tx indicates Transmit. receive Indicates the downstream traffic received from the start to the present. Transmit Indicates upstream traffic transmitted from the start to the present. In INTTERFACE, when we view the traffic of a WAN NIC, RX is downlink traffic and TX is uplink traffic. In SIMPLEQUEUES, this occurs when the destination address is a workstation IPIf the NIC is WAN, TX indicates the downstream traffic limit.
TX stands for Send. A transmitter (TX) is used to send signals or data. It can be regarded as a device that converts digital or electrical signals into radio waves or cable transmission signals. TX is used to convert data or information in a computer or other device into signals or data packets so that they can be received by other devices. The difference between RX and TX is conceptually, TX and RX are opposites of each other.
Lithium battery pack has 5 lines, two thick lines red and black are positive and negative power supply, the other three are signal detection lines, judge the battery voltage is too low or too high, play a role in protecting the battery. Charger charging, the positive terminal is connected to the red line, the negative terminal is connected to the black line. So you can charge it. Lithium battery is a class of lithium metal or lithium alloy as a positive/negative electrode material, the use of non-aqueous electrolyte solution of the battery.
TX/RX is the sending end and the receiving end, GND is the ground, VCC is the power supply, NC is not connected. This is a typical serial signal.
1, Qi certification: the universal language of Wireless charging industry Qi, the full name of the wireless charging Alliance (Wireless Power Consortium, referred to as WPC) masterpiece, it defines a global universal wireless charging standard. This standard is "convenient" and "universal" as the core, ensuring that different brands of products only need to have the Qi logo, can be seamlessly connected with any QI-compatible wireless charger.
2, the value of Qi certification certificate obtained Qi certified wireless chargers not only have high quality performance, but also mean that they comply with internationally recognized technical specifications and can be widely accepted worldwide. For consumers, choosing products with Qi certification means that they enjoy a stable, safe and efficient wireless charging experience.
3, the significance of Qi certification is to ensure the compatibility and interoperability between charging devices and mobile devices of different brands and manufacturers. In other words, as long as the device supports the Qi standard, wireless charging can be carried out on any charger with the Qi logo, without worrying about the combination between the charger and the deviceAllow the question.
4, Qi certification is WPC for wireless charging equipment product certification program. WPC tests the security, interoperability, and usability of specific features using a global network of independently licensed test LABS, each of which can involve multiple test procedures. Only Qi certified products can carry the Qi logo. The benefits of QI certification products that have not been tested and certified have safety risks, which may cause fever, burn the human body, cause fire, etc.
5, QI certification is the Wireless charging alliance certification, that is, WPC certification (Wireless? Power? The Consortium is a collaborative group of independent companies that aims to create and promote widespread market adoption of Qi, an international wireless charging standard compatible with all rechargeable electronic devices. QI certification is an authorized mark for wireless charging products, and only products that have been rigorously tested to ensure safety, interoperability and energy efficiency can use the QI certification mark.
