Product Advantages and Features of the Wireless Module
Wireless data transmission is widely used in fields such as vehicle monitoring, remote control, telemetry, small wireless networks, wireless meter reading, access control systems, community paging, industrial data acquisition systems, wireless tags, identity recognition, contactless RF smart cards, small wireless data terminals, security fire systems, wireless remote control systems, biological signal acquisition, hydrological meteorological monitoring, robot control, wireless 232 data communication, wireless 485/422 data communication, digital audio, digital image transmission, etc.
As the core of wireless data transmission, the wireless module has made rapid progress in recent years with the development of IoT and big data collection, and a variety of modular products have emerged.
Characteristics of wireless module manufacturers' Products
To produce modules that are compatible with wireless chip manufacturers, it is necessary to use high-reliability crystal oscillators, precision resistor-capacitor components, and reasonable inductance matching to handle RF interference, especially at the antenna end, which requires ample RF design experience and analog design foundation.
Even for copying the wireless module currently in mass production, the size of the module must be considered at the application end, whether it meets the requirements of increasingly small products, and whether the distance and power consumption are properly handled. Each module manufacturer has its own technical indicators and evaluation standards, and it is difficult to guarantee consistency from a production perspective.
Based on the current problems faced by the wireless module, such as low power consumption, small size, consistency in mass production, and ease of use during use.
Product advantages of wireless module
Firstly, from the perspective of module size, wireless modules have obvious advantages in terms of miniaturization. In today's trend towards miniaturization of terminal products, they can save more precious space for terminal products and meet customers' growing demand for small-sized product designs.
Secondly, from the perspective of mass production consistency, the wireless module uses high-reliability discrete components integration and avoids the RF processing problems of the wireless module at the circuit board level, which helps to improve the product performance of the wireless module. From the beginning of product packaging, the matching of discrete components and the stability of technical indicators are strengthened. In contrast, conventional wireless module varies greatly in the selection of components, making it difficult to guarantee the consistency of module mass production and the stability of the final product application.
Thirdly, in terms of the ease of use of the wireless module, they are based on QFN chip-level packaging. For engineers who are proficient in chip packaging, the need to grasp irregular module sizes is eliminated, and the overall cleanliness of the circuit board is optimized. The wireless module itself has an SPI interface that can communicate directly with a microcontroller. Apart from the need to add a decoupling capacitor and an antenna, there is no need to add any professional wireless design. For new design personnel, the difficulty of application development of wireless modules is greatly reduced.
