A port expander is a computer hardware device that allows a single port or connection to be expanded into several ports or connections. This device can be used to increase the number of available ports on a computer system, allowing multiple peripherals to be connected to the same port. The port expander also helps manage data transfer between connected devices, keeping all the data flowing in an orderly manner.
MikroElektronika’s port expander is a plug-and-play device that can be used to easily add additional ports to computers and other devices. It features 8-bit, I2C and SPI communication options, making it compatible with a wide range of microcontrollers. The device also offers galvanic isolation and power supply buffering, making it reliable and robust in demanding environments.
In addition, the port expander allows multiple peripherals to be connected to the same port, reducing cable clutter and removing the need for multiple USB ports. The device also features ESD protection and enhanced signal integrity, as well as 3.3V and 5V power supply capability and labeling options.
