KiCad PCB automation toolkit — automated placement, routing, scoring, and experiment management for KiCad projects via the pcbnew Python API.

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. The deterministic…

ESP32S3 ENV NODE: common questions

What microcontroller does the ESP32S3 ENV NODE use?

The ESP32S3 ENV NODE is built around the ESP32-S3-MINI-1-N8, from the ESP32 family.

How big is the ESP32S3 ENV NODE PCB?

The ESP32S3 ENV NODE measures 55.1 × 37.1 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the ESP32S3 ENV NODE?

17 components, from 12 distinct parts. The full bill of materials is listed on this page.

Where can I download the ESP32S3 ENV NODE 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 ESP32S3 ENV NODE 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 ESP32S3 ENV NODE 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.
