Guides for the things that actually go wrong, written so you can follow them at eleven at night with a breadboard in front of you.

No prior knowledge assumed
Real parts, real prices

## When it doesn't work

Start here if something is already built and misbehaving.

- [Your ESP32 reboots the moment the motor starts](https://soldr.ai/docs/esp32-reboots-when-motor-starts) — the brownout, and the five steps that fix it.

> **More guides are being written** — Reading serial output, photographing your breadboard for a diagnosis, and sketches that will not compile are next.

## Designing a build

Start here if you have an idea and no parts yet.

> **In progress** — Parts that fit together, what else you'll need, wiring and pins, the schematic, and buying a whole build as one kit.

## Screens and dashboards

> **In progress** — Pixel Studio, screen layout, and previewing the dashboard your board will serve.

## Still stuck?

Ask Soldr directly — paste your serial output or photograph the board. Questions and troubleshooting don't cost credits.
