The purpose of serial communication

The serial port is a kind of interface. The purpose is very clear in the title, which is “communication”. Just like calling, sending QQ, and sending WeChat, the sending method is also very similar. Whatever data is sent by the sender, the receiver will receive the data.micro bluetooth module This is called transparent transmission, or “transparent transmission” for short.

 what circumstances is the multi-serial port server used?

The multi-serial server is a converter between multiple asynchronous serial ports RS232/422/485 and Ethernet. It is an independent smart device with CPU, embedded operating system and complete TCP/IP protocol stack. Complete bidirectional transparent data transmission between RS232/422/485 and Ethernet, and allow multiple RS232/422/485 serial port wireless transceiver module devices to access the network immediately. RS232/RS485 devices are immediately upgraded to … Continua a leggere

The higher the Bluetooth version, the better the user experience?

Although the current Bluetooth version is updated very quickly, for true wireless headsets, is it true that the newer the Bluetooth version, the better the user experience? You may be able to see from the above that the higher the Bluetooth version, the stronger the function, the more applications, and the better the performance. But what also needs to be … Continua a leggere

Wi-Fi is often too slow?

For some large and medium-sized wireless coverage projects, problems involving unreasonable channel planning and co-channel interference will cause problems such as network delay and network instability. Channel selection is very important, and appropriate channel planning can reduce network interference. and unstable. Wireless network signals propagate in the air with electromagnetic waves, using two frequency bands of 2.4G and 5G, for … Continua a leggere

Whether the urban lighting project is well done or not

Whether the urban lighting project is well done or not, there are several key information, such as reflecting urban art,WiFi Wireless Module  humanistic characteristics and so on. However, if each place blindly pursues independent characteristics, it will only make the city night scene more varied and unable to reflect humanistic feelings. The implementation of a city’s lighting project is closely … Continua a leggere

Talking about Integrated Operational Amplifier and Typical Operational Amplifier Circuit

The integrated op amp is a multi-stage circuit with extremely complex interior. Usually, in circuit design, we only need to master the relevant characteristics of the integrated op amp.
