The OndselSolver library for assembly constraints and multibody dynamics is used by FreeCAD 1.0.0 for its new Assembly workbench.

This package contains all part definitions that are required for Fritzing app.

Gaf stands for “gschem and friends”. It is a subset of the entire tool suite grouped together under the gEDA name. gEDA/gaf is a collection of tools which currently includes: gschem, a schematic capture program; gnetlist, a netlist generation program; gsymcheck, a syntax checker for schematic symbols; gattrib, a spreadsheet programme that manipulates the properties of symbols of a schematic; libgeda, libraries for gschem gnetlist and gsymcheck; gsch2pcb, a tool to forward annotation from your schematic to layout using PCB; some minor utilities.

This library contains C++ code and Python3 bindings for creating a socket in a thread and using this socket to send and receive messages based on the Protocol Buffers library. It is designed to facilitate the communication between Cura and its backend and similar code.

WireViz is a tool for easily documenting cables, wiring harnesses and connector pinouts. It takes plain text, YAML-formatted files as input and produces beautiful graphical output thanks to GraphViz. It handles automatic BOM creation and has a lot of extra features.

Scikit-rf, or skrf, is a Python package for RF and Microwave engineering.

Microcom is a minimalistic terminal program for accessing devices via a serial connection. It features connection via RS232 serial interfaces (including setting of transfer rates) as well as in telnetmode as specified in rfc2217 and a (Linux specific) CAN mode.

This package contains the official KiCad schematic symbol libraries.

The audio measurement system is a system for audio measurement through sound card. It contains: generator, oscilloscope, audio spectrum analyzer (FFT) and frequency sweep plot.

cutecom is a graphical serial terminal, like minicom. It is aimed mainly at hardware developers or other people who need a terminal to talk to their devices.

Harminv is a free program (and accompanying library) to solve the problem of harmonic inversion — given a discrete-time, finite-length signal that consists of a sum of finitely-many sinusoids (possibly exponentially decaying) in a given bandwidth, it determines the frequencies, decay constants, amplitudes, and phases of those sinusoids.

LibreCAD is a 2D Computer-aided design (CAD) application for creating plans and designs.

FreeCAD is a general-purpose, feature-based, parametric 3D modeler for CAD, MCAD, CAx, CAE, and PLM. It is aimed directly at mechanical engineering and product design but also fits a wider range of uses in engineering, such as architecture or other engineering specialties. It is modular, allowing for extension and customization.

This package contains the official KiCad footprint libraries.

GNU PCB is an interactive tool for editing printed circuit board layouts. It features a rats-nest implementation, schematic/netlist import, and design rule checking. It also includes an autorouter and a trace optimizer; and it can produce photorealistic and design review images.

SOLVESPACE is a parametric 3D CAD tool. Applications include:

• modeling 3D parts — draw with extrudes, revolves, helixes and Boolean (union / difference / intersection) operations

• modeling 2D parts — draw the part as a single section, and export DXF, PDF, SVG; use 3D assembly to verify fit

• 3D-printed parts — export the STL or other triangle mesh expected by most 3D printers

• preparing CAM data — export 2D vector art for a waterjet machine or laser cutter; or generate STEP or STL, for import into third-party CAM software for machining

• mechanism design — use the constraint solver to simulate planar or spatial linkages, with pin, ball, or slide joints

• plane and solid geometry — replace hand-solved trigonometry and spreadsheets with a live dimensioned drawing

OpenCTM is a file format, a software library and a tool set for compression of 3D triangle meshes. The geometry is compressed to a fraction of comparable file formats (3DS, STL, COLLADA...), and the format is accessible through a simple API

This package contains the official KiCad project and worksheet templates.

PyVISA-py is a backend for PyVISA that implements most of the methods for Message Based communication (Serial/USB/GPIB/Ethernet) using Python and some well developed, easy to deploy and cross platform libraries.

Lib3MF is a C++ implementation of the 3D Manufacturing Format (3MF) file standard. It offers a way to integrate 3MF reading and writing capabilities, as well as conversion and validation tools for input and output data. The specification can be downloaded at http://3mf.io/specification/.

This package provides an OPC UA / IEC 62541 client and server for Python and pypy3.

The system call intercepting library provides a low-level interface for hooking Linux system calls in user space. This is achieved by hot-patching the machine code of the standard C library in the memory of a process.

Libfive is a tool for programmatic computer-aided design (CAD). In libfive, solid models are defined as Scheme or Python scripts, and there are no opaque function calls into the geometry kernel: everything is visible to the user. Even fundamental, primitive shapes are represented as code in the user-level language.

Capstone is a lightweight multi-platform, multi-architecture disassembly framework. Capstone can disassemble machine code for many supported architectures such as x86, x86_64, arm, arm64, mips, ppc, sparc, sysz and xcore. It provides bindings for Python, Java, OCaml and more.
