An Insight into WiFi Module with UART Interface

The modern era is all about Wireless RF embedded experience permitting data transmission between two devices wirelessly through radiofrequency. A WiFi module with UART interface is a part of convenient software that has the potential to execute different wireless arrangements. Some of the highly professional companies like Skylab are offering this amazing product at an affordable cost. WiFi module has become an integral part of modern-day wireless communication. It allows local area networks to operate without a conventional system of wiring and cables.

WiFi endorses a wireless technology that connects IoT devices including tablets, computers, smartphones, etc. to the internet. The radiofrequency emitted from a wireless router to a nearby device interprets the signal into data.

The users can see and use the data efficiently. A UART (Universal Asynchronous Receiver/Transmitter) is a microchip with built-in programming. It is one of the simplest forms of device-to-device digital communication.

However, it is not a communication protocol, but a type of physical circuit in a stand-alone IC. UART chiefly controls a computer's interface to its attached serial devices to transmit and receive serial data. It receives the bytes from the computer along with parallel circuits and transforms them into a single serial bit stream for outbound transmission.

What Does IoT WiFi modul with UART Interface Support?

The module supports the addition of secure and interoperable WiFi functionality. It usually incorporates two Ethernet serial ports integrates a basic AT command set for wireless products. It is an 802.11 b/g/n compliant module and offers WiFi networking and a TCP/IP stack. In this way, it enables simplified WiFi integration into any MCU-based consumer product.

Features of WiFi Modul with UART Interface

The internally integrated operating system provides a complete solution for WiFi networking through supporting serial port transparent transmission. Its main features are:

Supports IEEE802.11b/g/n wireless standards

The 802.11 b/g/n is an extension to the 802.11 specifications and a standard set for Wireless Local Area Networks (WLANs). It controls data transmission over short distances. The maximum network bandwidth is 54 Mbps in the 2.4 GHz bands.

Supports TCP/IP/UDP network protocols

TCP/IP stands for Transmission Control Protocol/ Internet Protocol. This model offers a highly reliable and end-to-end byte stream over unreliable internetwork. It determines the way a specific computer connects to the internet for the transmission of data. UDP employs a simple transmission method for ordering, reliability, or data integrity.

Supports UART/GPIO/Ethernet data interface

The high-performance module launched by Skylab supports the 802.11b/g/n protocol. Customers do not need to go into the details of UART/GPIO/Ethernet Data Communication Interface protocol to connect devices. With high-performance modules, the traditional applications are easily accessible to the wireless network through UART or 100M Ethernet interface.

An example of such a WiFi module is SKYLAB LCS6260 IOT UART Wifi Module With Low Power Application Processor

802.11 Wireless Standards
IEEE StandardFrequency/ MediumSpeed
802.112.4GHz RF1 to 2Mbps
802.11a5GHzUp to 54Mbps
802.11b2.4GHzUp to 11Mbps
802.11g2.4GHzUp to 54Mbps

Supports work as STA/AP/AP+STA mode

The low-cost high-performance module supports a complete WiFi protocol configuration utility incorporating STA/AP/AP+STA mode.

Supports router/bridge mode networking

The bridge mode connects two routers without degrading the performance by disabling the NAT feature on the modem. It avoids IP address conflict besides extending the WiFi coverage at home/ office.

Supports external/internal antenna

All features get a boost by a built-in antenna, external antenna connector, and an interface port to the carrier board. The WiFi module has a built-in internal antenna. The need for an external antenna arises where there is a possible issue of a GPS signal. 

Supports transparent transmission mode

The transparent transmission mode keeps the data the same during data transmission through the WiFi module. The transparent transmission process ensures the quality of data transmitted.

Supports AT+ instruction set for configuration

The AT+ command configures the ESP8266 WiFi Module with UART interface in Soft Access Point (AP) Mode. 

Supports friendly web configuration page

The WiFi module supports a friendly web configuration page to avoid confusing functionality.

Supports Palmodic signal

This function determines if the WiFi module is active, alive, or needs to reboot.

Supports UART auto-frame function

The WiFi module auto frames the data received from the UART port according to the auto-frame trigger length and auto-frame trigger time parameters. It sends the data to the network as a pre-defined data structure.

Operates on a single +3.3V power supply

Usually, the digital electronic components and circuits operate on 3.3V+/-10% power.

Average dimensions feature a small size of 24.0mm x16.0mm x 2.4mm

The device is amazingly compact and needs a lot less space to occupy.

FCC/CE/RoHS/TELEC certificated

The radiofrequency devices in the US comply with Federal Communication Commission certification. Furthermore, the device features RoHS compliance (lead-free).
