KiCraft is a multi-layer pipeline. Top-down:

1. KiCraft (Claude Code skill + Python helpers) -- turns a natural- language project description into the hierarchical KiCad 9 file set (root + leaf .kicadsch, .kicadpro, autoplacer.json). The LLM- driven stages (intent / functionalspec / architecture / bom) run as a Claude Code skill at .claude/skills/kicraft/, so a Claude Code subscription pays for inference and no API key is required.

AN ESP32 S3: common questions

What microcontroller does the AN ESP32 S3 use?

The AN ESP32 S3 is built around the ESP32-S3-MINI-1-N8, from the ESP32 family.

How big is the AN ESP32 S3 PCB?

The AN ESP32 S3 measures 188.1 × 58.2 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the AN ESP32 S3?

36 components, from 17 distinct parts. The full bill of materials is listed on this page.

Where can I download the AN ESP32 S3 design files?

From the laforestlabs/KiCraft repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the AN ESP32 S3 design in my own project?

The repository has no license, so all rights stay with laforestlabs. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the AN ESP32 S3 without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug ESP32 firmware against it before you order a PCB.
