Describe the project
Write what the board has to do, in plain language. Name the parts you care about and leave the rest open.
A USB-C powered ESP32-C3 board with a BME280 over I2C, a status LED and four mounting holes, 50 by 30 mm, two layers.State what matters: a size, a layer count, mounting holes, a connector that must sit on an edge. Stated facts are carried through to the board and are not overridden.

Answer the follow-ups
The studio asks the questions a design engineer would ask before starting: supply voltage, which interfaces are exposed, what the connectors are. Short answers are fine.
4
Review the schematic
The run shows each stage as it finishes: parts research, synthesis, the electrical checks, the design review. The schematic is rendered sheet by sheet. If a part could not be sourced or a check failed, the finding is listed with the reason.Use the chat to change anything: swap a part, add a header, change a footprint. Each change is re-checked.

The board runs on its own
After a passing schematic, placement and routing start automatically. Routing takes minutes, longer on dense boards. You can close the page; a finish email tells you when the board is done.The board is shown in 3D. Drag to orbit it. The report shows the DRC result and the connectivity result.

Download
The downloads panel lists the KiCad project, the schematic, the board, the priced BOM and the 3D model.Gerbers, drill files and the assembly bundle appear only when the board has zero DRC errors and every net is connected. If the board did not close, the report says which nets are open and the chat agent can diagnose and re-run it.
