Overview
Projectpcb is an open-source printed circuit board by AntacidDT, from the AntacidDT/TBDBreakout repository on GitHub, published under the CERN-OHL-S-2.0 licence. It is a 2-layer board of 48.3 × 35.6 mm with 18 parts on 21 nets, routed with 96 tracks and 0 vias.
It is built around the TBD62003APG. Its parts include 8 resistors, 4 diodes, 4 connectors and 2 capacitors.

README.mdBreakout for the TBD62003APG Board
This board is licensed CERN-OHL-S, and is meant to be a breakout PCB board for the TBD62003APG to 28BYJ-48 stepper motor.
License
This board may be used freely, but if distributed or modified it should be licensed as CERN-OHL-S aswell. You should've been given a copy of the License with this repository.
Why did I make this
I made this because even tho the ULN2003A Breakout PCB's are good, the TBD62003APG is a lot more efficient, thus I figured a breakout made for TBD62003APG could be very useful for everyone.
Where to get the PCB gerbers
A Zip folder is found at /pcbgerbers/tbd62003apg_gerbers.zip, and if you want the raw PCB gerber files, its found at /pcbgerbers/rawpcbgerbers. The PCB gerbers use Protel Filenames because many PCB manufacturers recommend and highly prefer Protel Filename Extensions instead.
Thanks for reading :))
Also this repository is often short for what I do, but I released this to github purely to share it to the community for free and make a positive impact.

Questions
How big is the Projectpcb PCB?
It measures 48.3 × 35.6 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Projectpcb use?
18 parts, built around the TBD62003APG. 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 Projectpcb KiCad files?
From the AntacidDT/TBDBreakout repository on GitHub, at the commit this page was made from: the board is projectpcb/projectpcb.kicad_pcb and its schematic projectpcb/projectpcb.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Projectpcb design in my own project?
Its repository publishes it under the CERN-OHL-S-2.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
