mbpoll is a command line utility to communicate with ModBus slave (RTU or TCP).

LibrePCB is Electronic Design Automation (EDA) software to develop printed circuit boards. It features human readable file formats and complete project management with library, schematic and board editors.

Iaito is the official graphical interface for radare2, a libre reverse engineering framework. Iaito focuses on simplicity, parity with commands, features, and keybindings.

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

GNU LibreDWG is a C library to handle DWG files. It aims to be a free replacement for the OpenDWG libraries.

LibCharon is a Python file metadata and streaming library. It belongs to the Cura project from Ultimaker.

Manifold is a geometry library dedicated to creating and operating on manifold triangle meshes. A manifold mesh is a mesh that represents a solid object, and so is very important in manufacturing, CAD, structural analysis, etc.. Manifold also supports arbitrary vertex properties and enables mapping of materials for rendering use-cases.

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

This package contains the official KiCad project and worksheet templates.

scad-dbus allows controlling OpenSCAD from within Emacs via D-Bus without having to switch programs or reach for the mouse.

This package provides a full Python driver for the Keithley 2600B series of source measurement units. This driver provides access to base commands and higher level functions such as IV measurements, transfer and output curves, etc. Base commands replicate the functionality and syntax from the Keithley's internal TSP Lua functions.

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

Lcapy is a Python package for linear circuit analysis. It uses SymPy for symbolic mathematics.

Lcapy can symbolically analyse circuits described with netlists or by series/parallel combinations of components. It can also manipulate ontinuous-time and discret-time expressions.

LinSmith is a Smith Charting program, mainly designed for educational use. As such, there is an emphasis on capabilities that improve the 'showing the effect of'-style of operation.

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.

This package provides a pipeflow calculation tool that complements pandapower in the simulation of multi energy grids.

PrusaSlicer takes 3D models (STL, OBJ, AMF) and converts them into G-code instructions for FFF printers or PNG layers for mSLA 3D printers. It is compatible with any modern printer based on the RepRap toolchain, including all those based on the Marlin, Prusa, Sprinter and Repetier firmware. It also works with Mach3, LinuxCNC and Machinekit controllers.

Fastcap is a capacitance extraction program based on a multipole-accelerated algorithm.

MeshLab is a system for the processing and editing of large, unstructured, 3D triangular meshes. It is aimed to help the processing of the typical, not-so-small unstructured models arising in 3D scanning, providing a set of tools for editing, cleaning, healing, inspecting, rendering and converting this kind of meshes. These tools include MeshLab proper, a versatile program with a graphical user interface, and meshlabserver, a program that can perform mesh processing tasks in batch mode, without a GUI.

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 repository contains the official KiCad documentation.

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 provides platfrom-independent types, macros and a fallback for environments without libc for Zydis.

Python bindings for orocos-kinematics-dynamics.
