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

Please update your readme with the right pcb design!

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 wasn’t 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 won’t be either.

I think it will take at most 3–4 posts, including corrections. I checked all the important things. In total, there are only three integrated circuits anyway, haha.
