Your BOM should just be BOM.csv, not BOM.csv.txt. Addtionally, it seems like you're not asking for funding?

Fixed PCB
I noticed that connecting the wires to my connectors would be impossible, so I had to change the board's appearance. Now everything works. That was easy j*b

Routed the PCB
With this stage, the PCB design finally came together.
All the traces on the board are now fully connected. Most of the heavy lifting had already been done back in the schematic phase, so routing turned out to be a pretty smooth process overall.
I focused on keeping the layout clean and organized β grouping related signals, minimizing unnecessary vias, and giving the power lines enough width to ensure stable operation.
After running a final DRC, everything checked out with no issues.

Made Schematics
During this stage, I worked on creating the schematic for the PCB.
It wasnβt too difficult, because β as I mentioned β the design includes only three main modules, while the remaining parts are simple components, which made the process much easier.

First Steps
In this stage, I focused on understanding how the converter will work.
It's not difficult, and the overall project structure wonβt be either.
I think it will take at most 3β4 posts, including corrections. I checked all the important things. In total, there are only three integrated circuits anyway, haha.
