In 2020, a sudden epidemic disaster struck, and the major economic markets were pressed to varying degrees with a “pause button”. The Internet of Things control is highlighted as an advantage in the emerging industry. Its contactless interaction, remote control, and intelligent control of the workshop bring a safe and intelligent life experience to the people during the epidemic. Most of these IoT controls use gateway information bridges to transmit—wifi routing modules.
But do you know? Engineers want to choose a cost-effective wifi routing module for serial port transparent transmission. They have to know the two major differences between wifi routing modules: mcu + wifi module and CPU + wifi module. Recently, customers have always asked about the difference, and now I will arrange it for you.
Mcu + wifi module is abbreviated as single chip and wifi module integrated master control. It is a single-thread routing module with only one serial port. It means that only one instruction can be transmitted while transmitting instructions. Commands such as the on and off commands of the smart switch. Simply, it can also be used as a simple router, but the broadband is relatively small and the network speed is relatively slow. Power consumption and price will be relatively low. At present, more modules such as ESP8266 are used in the market.
The CPU + wifi module is referred to as the main control of the system set wifi module, which is a wifi routing module that can simultaneously process instructions in multiple threads, that is, multiple instructions are simultaneously issued and processed at the same time when the instructions are transmitted. The core master is equipped with Linux system, there are many hardware interfaces, multiple serial ports transparent transmission, and 5 network ports can also be automatically branched. The bandwidth is relatively large, and more complicated instructions can be operated at the same time, such as wired to WiFi, 4G to WiFi, ceiling AP, 4G router, wireless speakers, wireless storage expansion, wireless image transmission, data transmission, industrial routers, wifi printers, etc. . The power consumption and price are relatively high. Currently, 4G LTE can be transferred to WiFi or network port, serial port data transparent transmission, WiFi-audio test, WiFi-U disk test, WiFi-image transmission test function.

Intelligentization has been applied to production in all walks of life, and I hope that the editor ’s article will help you in the selection of new products!
