How to Use Soldr

Go to soldr.ai and describe what you want to build, in ordinary words. That's the entire starting point — no part numbers, no board name required if you don't have one in mind yet.

Starting a build

Type the idea as a sentence: "a plant watering system that texts me when the tank is empty," or "a doorbell that sends a photo to my phone." Soldr reasons about voltage, current draw, I²C addresses, pin capability, connectors, and budget before naming a single part, then returns a complete bill of materials, priced from Compoden's live stock.

If you already have a board sitting on your desk, say so — the wiring and firmware get built for the board you actually have, not a generic one.

Getting the rest of the build

• Wiring, pin by pin, for the specific board named — not a generic diagram that assumes a pinout your board doesn't have.
• An interactive schematic, not a photo of breadboard wires.
• Working firmware, for any of 674 supported board targets. Flash it straight from the browser over USB, or export it to the Arduino IDE, PlatformIO, or any other environment you already use.
• What the display shows, if the build has one — icons and animations for an OLED, LED matrix, or WS2812 ring, or a layout binding live sensor readings to the screen.

Asking questions mid-build

This is free at every stage, not just at the start. "Do I need a resistor here?", "Will 5V damage this part?", "Can I use the board I already own instead?" are all answered against your actual parts, not a generic answer pulled from training data.

If something isn't working, paste what your serial monitor is printing for a diagnosis grounded in the exact sketch that was flashed, or upload a photo of your breadboard and have the wiring checked connection by connection against the plan.

Buying the parts

A complete build can be bought as a single kit rather than tracked down as separate line items, through Compoden, Soldr's sibling store. Every part named is something Compoden actually stocks in India, at a live price.

What it costs

Twenty-five credits are granted free on sign-in. Questions, explanations, troubleshooting, and diagnosis never cost anything — only generated firmware code spends credits, billed by the size of what's generated, and there's no subscription.
