ImShyMike/uSDReader1Micro SD to USB A adapter PCB
USDReader is an open-source printed circuit board by ImShyMike, from the ImShyMike/uSDReader repository on GitHub, published under the GPL-3.0 licence. It is a 2-layer board of 54.2 × 27 mm with 33 parts on 42 nets, routed with 210 tracks and 37 vias.
It is built around the USB2244I-AEZG-06-TR, LM1117MP-3.3 and TPD2EUSB30DRTR. Its parts include 12 capacitors, 10 resistors, 2 ICs, 2 diodes and 2 connectors. It belongs with the interfaces and adapters boards of this library.
A simple micro SD to USB A adapter PCB mad eusing KiCAD.
(some components dont have 3D models because im too lazy to find them)

33 parts, built around the USB2244I-AEZG-06-TR, LM1117MP-3.3 and TPD2EUSB30DRTR. 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.
From the ImShyMike/uSDReader repository on GitHub, at the commit this page was made from: the board is PCB/uSDReader.kicad_pcb and its schematic PCB/uSDReader.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Its repository publishes it under the GPL-3.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
