Show HN: An LLM-Powered Tool to Catch PCB Schematic Mistakes

Somewhat related: a while ago I was working on a project and wanted to use an RS485 to TTL conversion board which came with badly translated instructions. However, somebody had reverse engineered the design and uploaded an EasyEDA schematic. I shoved the raw JSON for the schematic (which looked quite cryptic to me) into Gemini 2.5 Pro and asked it if it could understand it, and it cheerfully responded with:

> Of course, Jack. I can understand the schematic from the provided JSON file. It describes an RS485 to TTL Converter Module. > Here is a detailed breakdown of the circuit's design and functionality

...followed by an absolutely reasonable description of the whole board. It was imprecise, but with some guidance (and by putting together my basic skills with Gemini's vast but unreliable knowledge) I was able to figure out a few things I needed to know about the board. Quite impressive.

In general, there are always "better" solutions to any problem, but finding the right balance for your budget is the key.

If doing industrial work, than consumer-grade workmanship / LLM-slop is usually unacceptable. Start with the FTDI firmware tool and an isolation chip App-note...
