The difference

A design you can actually build.

Most tools name a component and leave you to find it. Soldr picks parts that exist, work together, and are on a shelf right now. One sentence in, this out:

Click buy and we ship the parts straight to you. No hunting across five sites, no substitutions that do not fit.

What it does

The whole bench, in one place.

Say the idea in plain words. Everything below comes out of that one sentence, and you can keep asking until it's right.

The parts

A build spec'd from a sentence, using parts that exist and fit together.

The wiring

Every connection, pin by pin, for the board you named.

The schematic

A real circuit diagram, not a photo of breadboard wires.

The code

Firmware for 674 boards, compiled before you get it.

Pixel Studio

Draw icons, QR codes and animations for an OLED, an LED matrix or a WS2812 ring. What glows on screen is what lights up on the part.

Screen layout

Drag text, bars and icons onto your display and tie them to real readings. The firmware rewrites itself to match.

Dashboard preview

See the web page your board will serve — before you have bought a single part.

Answers

Why is my reading drifting? Which sensor? Does this need a resistor? Ask anything, any time.

Once the parts arrive it keeps going — setup, testing, a serial plotter to watch it run, and troubleshooting for the thing you actually bought.

Does it actually work

Yes. We check.

Your code is built on a real compiler before you see it. If it fails, Soldr fixes it first — and the fix is free.
