[Successful test] Motherboard USB2.0 9pin adapter

Overview

Using this adapter, you can directly convert the 9-pin socket of the motherboard ( almost any motherboard ) into 2 USB2.0 sockets!
It is very convenient for you to use the USB2.0 data cable to connect to the USB2.0 panel on the front of the chassis!
At the same time, a USB flash drive can also be built into the chassis . (Applicable to situations where some industrial computers, Synology and other machines require U disks to be plugged in at all times)
You can also put a wireless mouse and keyboard into the case, making full use of the idle interfaces in the case without occupying external interfaces, which is beautiful.

The measured speed is the same as that of native USB2.0. The speed does not reach 40mb/s, which may be because the test platform is too old.
Note that in order to save costs, low-cost universal female headers are directly used, so there is no fool-proof design . Vertical lines are drawn on the silk screen of the fool-proof bits on the PCB . It is recommended to use a soldering iron to flatten the fool-proof bits or block them with something when welding.
The fool-proof bit in the uploaded picture was reversed and has been corrected.
