Half hole WiFi Module PCB

wifi module, also known as serial port Wi Fi module, belongs to the Internet of things transmission layer. Its function is to convert the serial port or TTL level into an embedded module conforming to Wi Fi wireless network communication standard, with built-in wireless network protocol ieee802.11b.g.n protocol stack and TCP / IP protocol stack. Traditional hardware devices embedded in Wi Fi module can directly use Wi Fi to connect to the Internet, which is an important part of the realization of wireless smart home, M2M and other Internet of things applications.

wifi module PCB can be divided into three categories: 1. General Wi Fi module PCB, such as mobile phone PCB, notebook PCB, tablet PCB.

The USB or SDIO interface module on the brain, Wi Fi protocol stack and driver run in Android, windows, IOS system, which requires a very strong CPU to complete the application; 2, the router scheme Wi Fi module, which is typically a home router, protocol and driver is with the help of chips with powerful flash and ram resources and Linux operating system; 3, embedded Wi Fi module, 32-bit single-chip microcomputer, in Set Wi Fi driver and protocol, interface for general MCU interface such as UART. Suitable for all kinds of smart home or smart hardware products.
