Abstract

The invention provides multi-channel serial port equipment based on USB-HUB, which comprises a USB-HUB chip; the USB-HUB chip is connected with a computer host through a USB, and a power conversion circuit is arranged between the computer host and the USB-HUB chip; the USB-HUB chip is connected with a plurality of USB serial port chips for connecting equipment. According to the device, multiple serial port debugging devices are integrated together, the conditions of tedious wiring, insufficient USB ports and insufficient wires in the debugging process of developers are avoided, higher efficiency is provided for the developers, practicability is high, and market popularization is facilitated.

Description

technical field [0001] The invention relates to the technical field of PCB hardware design, in particular to a USB-HUB-based multi-channel serial port device. Background technique [0002] With the development of social economy, people's requirements for the quality of life are also increasing day by day. The functional requirements of various living equipment are increasing, the reliability is improving, and the functions are becoming more and more complex. Therefore, developers need better debugging equipment, and the mainstream single Serial ports are no longer sufficient for today's developers. [0003] Therefore, there is an urgent need for a USB-HUB-based multi-channel serial port device, which can solve the problem that the existing single serial port cannot meet the needs of developers. Contents of the invention [0004] The purpose of the present invention is to provide a multi-channel serial port device based on USB-HUB to solve the problem that the above-mentio...
