What's WiFi module?
WiFi module, also called a serial port Wi-Fi module, falls under the IoT transmission layer. It converts serial port or TTL levels into an embedded module that complies with Wi-Fi wireless network communication standards, with a built-in IEEE 802.11b/g/n wireless network protocol stack and TCP/IP protocol stack.
Embedded Wi-Fi modules enable traditional hardware devices to connect directly to the Internet via Wi-Fi, and are key components for realizing IoT applications such as smart homes and M2M (Machine-to-Machine) communication.
General-Purpose Wi-Fi Module PCBs: Examples include the USB or SDIO interface modules on mobile phones, laptops, and tablets. Their Wi-Fi protocol stacks and drivers run on Android, Windows, and iOS systems, requiring a highly powerful CPU to support applications.
- Router-Solution Wi-Fi Module PCBs: Typical examples are home routers. Their protocols and drivers operate on chips with ample flash memory and Linux systems.
- Embedded Wi-Fi Module PCBs: They feature a 32-bit MCU, integrated Wi-Fi drivers and protocols, and use common MCU interfaces such as UART. They are suitable for various smart home and smart hardware products.

Managing kitting and packaging in-house can be time-consuming, costly, and error-prone.
Maybe an off-the-shelf cable can't meet your needs.
Twisting entwines multiple wires and arranges them tightly next to each other. Depending on the AWG size, we can group up to fifty conductors.
Shielding refers to the metallic layer surrounding a cable’s conductor, created to limit signal interference between the wire and external fields.
PCB manufacturing is the process of building a physical PCB from a PCB design according to a certain set of specifications.
The following design standards refer to the IPC-SM-782A standard and the design of some famous Japanese design manufacturers and some better design solutions accumulated in the manufacturing experience.
Via holes, also known as through holes, play a role in connecting different parts of a circuit board.
