IoT wireless module: what is a combination module

The Internet of Things is an important part of a new generation of information technology, and it is also an important stage of development in the “informatization” era. Its English name is: "Internet of things (IoT)". As the name implies, the Internet of Things is the Internet that connects objects. This has two meanings:

First, the core and foundation of the Internet of Things is still the Internet, which is an extension and expansion of the Internet.

Second, its user end extends and expands to any item and item for information exchange and communication, which means that the object rests. The IoT is widely used in the convergence of networks through intelligent sensing, recognition technology, and pervasive computing and other communication-aware technologies. It is therefore also known as the third wave of the development of the world's information industry following the computer and the Internet. The Internet of Things is an application extension of the Internet. It is not so much the Internet of Things as a network. It is better to say that the Internet of Things is a business and an application. Therefore, application innovation is the core of the development of the Internet of Things. Innovation 2.0, with user experience as the core, is the soul of the development of the Internet of Things.

In short, the Internet of Things connects objects in the real world to the Internet, making it easy for people and things to communicate with each other.

The RF wireless module is a modular product of digital radio and refers to a high-performance professional data transmission radio module realized by means of DSP technology and radio technology. The wireless module extends to many systems, industrial control switch io equipment, 485 wireless transmission equipment dw-m1, analog acquisition and control equipment. From the earliest use of key codes, telegrams, analog radio modules plus wireless MODEM, to the current digital radio module and DSP, software radio; transmission signal from code, low speed data (300 ~ 1200bps) to high speed data (N * 64K ~ N*E1).

Typical applications include: industrial automation, oilfield data collection, railway wireless communications, coal mine safety monitoring systems, pipe network monitoring, hydrological monitoring systems, and sewage treatment monitoring.

High-performance professional data transmission radio modules realized by means of DSP technology and radio technology are called wireless modules. Like WiFi modules and Bluetooth modules are all wireless modules. What is a combination module? This small compendium comes for everyone to elaborate on the next combination of modules.

We are familiar with the WiFi, Bluetooth module, GPS module is based on a communication module products, and modular modules are based on two or more modules.

1, WiFi + BLE Bluetooth combination module

Highly integrated WiFi + BLE Bluetooth combo combo module supports WiFi, BLE Bluetooth multiple data interfaces, WiFi and Bluetooth can transmit data through UART serial port.

2, WiFi + Bluetooth + BLE Bluetooth module

Bluetooth is divided into traditional Bluetooth and low-power Bluetooth, WiFi + Bluetooth + BLE Bluetooth module refers to the module WiFi support SDIO interface, Bluetooth support UART interface, support PCM Bluetooth peripheral transmission.

3, GSM / GPRS + GNSS combination module

Integrated high-performance GNSS, quad-band GSM/GPRS GSM/GPRS+GNSS module combination module.

4, car integrated navigation module

Using GNSS/INS integrated navigation and positioning technology, it can also provide vehicles with high-precision positioning and integrated navigation modules in tunnels, garages and other environments.

5, indoor and outdoor integration program

The mature GPS/BDS satellite positioning and mobile base station assisted positioning are still applied outdoors, while indoor uses Bluetooth positioning technology.

Selection of modular modules can be determined based on the actual wireless communication requirements of the product

P2.2X3 Automotive Right Angle Male Connector

P2.2X3 Automotive Right Angle Male Connector.Automobile connector is a kind of component that electronic engineers and technicians often contact. Its function is very simple: build a communication bridge between blocked or isolated circuits in the circuit, so as to make the current flow and realize the predetermined function of the circuit. The form and structure of automobile connector are ever-changing. It is mainly composed of four basic structural components: contact, shell (depending on the variety), insulator and accessories.
