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:

| Part | Role | Price |
|---|---|---|
| ESP32-C3 Super Mini | controller | ₹290 |
| Capacitive Soil Moisture Sensor V2.0 | moisture | ₹55 |
| 12V Solenoid Valve | the water | ₹240 |
| IRF540N MOSFET | 12V switch | ₹60 |
| LM2596 Buck Converter | 12V → 5V | ₹95 |
| 12V 2A DC Adapter | supply | ₹300 |
| Jumper Wire Combo | wiring | ₹60 |
| Everything you need | 7 parts | ₹1,100 |

**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
Working firmware for 674 boards, ready to flash from the browser.

### 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, then ask for the code and it comes back matching your layout.

### Dashboard preview
If your build serves a web page, see what it looks like 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.

Onto the board

## Flash it from your browser. Or take it to your own IDE.

Plug the board into your computer and flash it straight from the tab — nothing to install, nothing to configure. Or copy the sketch and open it in the Arduino IDE, PlatformIO, or whatever you already use.

**674**boards Soldr writes code for — plus sensors, motors, drivers and displays, with more added every week
