Turn your next BIG idea into a reality
Describe what you want it to do. Julius helps choose the electronic parts, arrange them on a board and connect them with copper. You review the design before downloading files for manufacturing.

The suppliers solderit.ai talks to.
Two, and they are different kinds of place. Which one a project uses changes how the board gets built, not only what it costs.
- JLCPCBAssembly
An assembler with a stocked library, not a distributor.
The parts come with an assembly option, subject to stock: a basic part costs nothing extra to place, an extended part carries a loading fee, and a part JLCPCB does not stock cannot be assembled there.
Prices and stock: From our own ingest of its catalogue, so as fresh as the last ingest.
- MouserComponents
A distributor that sells components and assembles nothing.
The components are sourced here and the assembly is arranged separately — by another assembler, or by you. Its catalogue is far larger than any assembler’s library.
Prices and stock: Read on each lookup and never stored; Mouser’s terms forbid keeping them.
A project chooses which of these it uses, and a part carries the supplier that quoted it.
Inside the example project
The board, parts list and manufacturing files from the walk-through above.
A design you can inspect
40 × 30 mm · 2 layers · 25 components
Designed to water a plant pot by itself: read soil moisture and temperature, and run a pump from a battery charged over USB-C or from a solar panel.
Inspect the component positions, pads and copper.
