Made in India
Describe your idea. Soldr takes it all the way — parts, wiring, schematic, code, the screen, the dashboard — and answers every question along the way. The parts it picks actually exist and are in stock.

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
Say the idea in plain words. Everything below comes out of that one sentence, and you can keep asking until it's right.
A build spec'd from a sentence, using parts that exist and fit together.
Every connection, pin by pin, for the board you named.
A real circuit diagram, not a photo of breadboard wires.
Working firmware for 674 boards, ready to flash from the browser.
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.
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.
If your build serves a web page, see what it looks like before you have bought a single part.
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
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.
Pricing
Buy credits when you want them. Nothing recurring, nothing to cancel, nothing tying you down.
Asking is always free. Questions, troubleshooting and help after you buy never cost credits — only generated code does. 1 credit = ₹1.
Suppliers
Soldr picks the parts for every build it designs, and we stock what it picks. If you make or distribute components, every build that specifies your part is stock we need to hold.
Your product list with wholesale prices, plus GST and PAN. We ask for bank details only after we accept you.
Added to the catalogue Soldr designs against, with your specs and your datasheets.
Repeat purchase orders as builds call for your parts. You supply us; we handle the customer.
