Description:
This is an USB MicroSD Card Reader mad with the GL823K IC.
The footprint of the SD card holder was made by me, and I made it by mistake with a solder mask cover, witch had to be removed from it before soldering the socket.
USB_MicroSD_CardReader V1.0
The first version was just for testing, trying to use the GPIO pin of the IC, but unfortunately, because of the poor quality of the datasheet, it didn`t worked.
USB_MicroSD_CardReader V2.0
At the second version, I remake the SD card holder footprint, added some holes for a 3D case and used differential pairs for the USB data lines.
Schematic:
Results:
I have to wait the second board to arrive, and to make the 3D case for it, but overall, the board work`s verry well, and I am very happy of how it turned out.

Questions
How big is the USB MicroSD CardReader PCB?
It measures 42.5 × 47.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the USB MicroSD CardReader use?
40 parts. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the USB MicroSD CardReader KiCad files?
From the Tonikiller10000/USB-MicroSD_CardReader repository on GitHub, at the commit this page was made from: the board is USB_MicroSD_CardReader/USB_MicroSD_CardReader.kicad_pcb and its schematic USB_MicroSD_CardReader/USB_MicroSD_CardReader.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the USB MicroSD CardReader design in my own project?
Its repository states no licence, so its author keeps all rights: ask Tonikiller10000 before reusing the design.
