What is an io extension module? IO expansion module is a hardware device used to expand the input/output functions of a computer or other device. According to different interface types and functions, IO expansion modules can be divided into many types. The following are some common IO expansion module types:
1. USB expansion module: Connected to a computer or other device through a USB interface, used to expand the number of USB interfaces or add other types of interfaces, such as USB to serial port, USB to Ethernet, etc. The price of USB expansion modules ranges from tens to hundreds of yuan, depending on the brand, model and function.
2. PCI expansion module: Uses a PCI slot to connect to the computer’s motherboard and is used to expand the number of PCI interfaces of the computer or add other types of interfaces, such as serial ports, parallel ports, Ethernet, etc. The price of PCI expansion modules is relatively low, usually ranging from tens to hundreds of yuan.
3. GPIO expansion module: used to expand the number of GPIO (General Purpose Input/Output) interfaces of the computer to connect external sensors, actuators and other devices. The price of GPIO expansion modules is relatively low, usually ranging from tens to hundreds of yuan.
4. Arduino expansion module: used to expand the input/output functions of the Arduino development board and add more pins, sensors, actuators, etc. The price of Arduino expansion modules varies depending on the brand, model and function, ranging from tens to hundreds of yuan.
The above are only some common types of IO expansion modules. In fact, there are many other types of expansion modules, such as SPI expansion modules, I2C expansion modules, etc. The specific type of IO expansion module to choose depends on your needs and the interface type of the device.
Regarding the price of IO expansion modules, the specific price needs to be determined according to the brand, model and function. Zongheng Intelligent Control’s newly released IO expansion module ET1010 supports head-to-tail cascading, non-inductive expansion, plug-and-play, and the price is only 169 yuan/unit. It can be purchased in bulk and can apply for a free trial.
The price range of IO expansion modules in the market basically ranges from tens to hundreds of yuan. You can find and compare different makes and models of IO expansion modules on electronics supplier websites to find one that suits your needs and budget.Recommended content: PLC IO expansion module
