KiCad PCB automation toolkit — placement, routing, scoring, and experiment management

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…

AN NRF52840 BLE: common questions

What microcontroller does the AN NRF52840 BLE use?

The AN NRF52840 BLE is built around the nRF52840-QIAA-R, from the Nordic nRF family.

How big is the AN NRF52840 BLE PCB?

The AN NRF52840 BLE measures 146.2 × 58.2 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the AN NRF52840 BLE?

25 components, from 16 distinct parts. The full bill of materials is listed on this page.

Where can I download the AN NRF52840 BLE 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 NRF52840 BLE 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 NRF52840 BLE without the hardware?

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