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…

SX1276 LORA NODE: common questions

What microcontroller does the SX1276 LORA NODE use?

The SX1276 LORA NODE is built around the STM32L051C8T6, from the STM32 family.

How big is the SX1276 LORA NODE PCB?

The SX1276 LORA NODE measures 119.4 × 93 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the SX1276 LORA NODE?

25 components, from 15 distinct parts. The full bill of materials is listed on this page.

Where can I download the SX1276 LORA 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 SX1276 LORA 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 SX1276 LORA NODE without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug STM32 firmware against it before you order a PCB.
