What is the difference between IoT module and chip? IoT modules and iot wifi module chips are well known high-tech products today. Almost all electronic devices are equipped with chips. So, what is the difference between IoT module and chip? What? To clarify this question, you need to know what chip and IoT module are first.
Chip, also known as microcircuit, microchip and integrated circuit (English: integrated circuit, integrated circuit). The silicon wafer containing the integrated circuit is small and is usually part of a computer or other electronic device.
Chips also have their own unique functions. Broadly speaking, a semiconductor wafer can be called a chip as long as it is made by microfabrication methods and does not necessarily have an internal circuit. In communications and information technology, when the scope is limited to silicon integrated circuits, the intersection of the chip and the integrated circuit is the circuit on the silicon wafer.
In the field of automatic identification, module is an abbreviation for 1D barcode scanning module and 2D barcode scanning module. The module is one of the important components of the secondary development. It has a complete independent scanning function and can be embedded in devices for cell phones, computers, printers, assembly lines and other industries.
IoT module plays an important role in the application of IoT technology. It is an important link between IoT cognitive layer and transmission layer. It is a necessary hardware configuration and cannot be replaced. All data information caused by IoT end devices are collected into computer network mechanical devices according to IoT module, and then monitored remotely according to electronic computers.
In the professional field, IoT modules are also known as wireless receiver modules. There are many types of wireless receiver modules. The commonly heard wireless modules are: Wi-Fi module, 4G module, Bluetooth module, NB-ioT module, Lora module and so on. The function of each wireless module is different. Wireless receiver modules are usually built into specific devices that connect to wireless networks and push and transmit data.
The module usually consists of a hardware PCBA board and embedded software, including the protocol stack.
Hardware PCBA board usually consists of baseband chip, RF circuit and antenna, power supply, shield and embedded software.
Embedded software includes the running software environment and protocol stack. As an example, the wireless network protocol IEE802 is built into the Wi-Fi module. 11bg.n protocol stack and TCP/IP protocol stack
Why not use chips and modules directly?
In the electronics industry, development cost and time determine whether customers choose to design their own chips or install modules directly. In the case of RF circuits and software development capabilities are small, most users will still choose modules. The end product is the whole product, no need to form a team to independently develop RF and wireless protocol functions.
At the same time, the risk is high. According to the principle of professionals doing professional things, outsource this matter to module manufacturers. Provide IoT hardware communication interface upward. Customers do not need to care about the internal logic, only the interface and parameter configuration information to provide a standard communication solution for the decentralized needs of IoT.
In addition, due to market competitiveness and the pursuit of high stability and reliability, module manufacturers will conduct rigorous testing of modules and even apply for relevant certifications, such as CE certification.
