It features an integrated environment for schematic capture, Printed circuit board, PCB layout, manufacturing file viewing, ngspice-provided SPICE, SPICE simulation, and engineering calculation. Tools exist within the package to create bill of materials, artwork, Gerber format, Gerber files, and 3D models of the PCB and its components. History Early history KiCad was created in 1992 by Jean-Pierre Charras while working at University_technical_institute_(France), IUT de Grenoble. The name came from the first letters in the name of a company of Jean-Pierre's friend in combination with the term Computer-aided design, CAD. KiCad originally was a collection of electronics programs intended to be used in conjunction with each other. The main tools were EESchema, PCBnew, a Gerber format, Gerber viewer, and a calculator. 2010 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Gerber Format
The Gerber format is an open, ASCII, vector format for printed circuit board (PCB) designs. It is the ''de facto'' standard used by PCB industry software to describe the printed circuit board images: copper layers, solder mask, legend, drill data, etc. The standard file extension is .GBR or .gbr though other extensions like .GB, .geb or .gerber are also used. It is documented by The Gerber Layer Format Specification and some related (but less universally supported) extensions such as XNC drill files and GerberJob to convey information about the entire PCB, as opposed to single layers. Gerber is used in PCB fabrication data. PCBs are designed on a specialized electronic design automation (EDA) or a computer-aided design (CAD) system. The CAD systems output PCB fabrication data to allow fabrication of the board. This data typically contains a Gerber file for each image layer (copper layers, solder mask, legend or silk...). Gerber is also the standard image input format for all ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ngspice
''Ngspice'' is an open-source mixed-level/ mixed-signal electronic circuit simulator. It is a successor of the latest stable release of Berkeley SPICE, version 3f.5, which was released in 1993. A small group of maintainers and the user community contribute to the ''ngspice project'' by providing new features, enhancements and bug fixes. Ngspice is based on three open-source free-software packages: Spice3f5, Xspice and Cider1b1: * SPICE is the origin of most modern electronic circuit simulators, its successors are widely used in the electronics community. * Xspice is an extension to Spice3 that provides additional C language code models to support analog behavioral modeling and co-simulation of digital components through a fast event-driven algorithm. * Cider adds a numerical device simulator to ngspice. It couples the circuit-level simulator to the device simulator to provide enhanced simulation accuracy (at the expense of increased simulation time). Critical devices can be d ...

EAGLE (program)
EAGLE is a scriptable electronic design automation (EDA) application with schematic capture, printed circuit board (PCB) layout, auto-router and computer-aided manufacturing (CAM) features. EAGLE stands for Easily Applicable Graphical Layout Editor () and is developed by CadSoft Computer GmbH. The company was acquired by Autodesk Inc. in 2016 who announced to support the product up to 2026 only. Features EAGLE contains a schematic editor, for designing circuit diagrams. Schematics are stored in files with .SCH extension, parts are defined in device libraries with .LBR extension. Parts can be placed on many sheets and connected together through ports. The PCB layout editor stores board files with the extension .BRD. It allows back-annotation to the schematic and auto-routing to automatically connect traces based on the connections defined in the schematic. EAGLE saves Gerber and PostScript layout files as well as Excellon and Sieb & Meyer drill files. These ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Linux
Linux ( ) is a family of open source Unix-like operating systems based on the Linux kernel, an kernel (operating system), operating system kernel first released on September 17, 1991, by Linus Torvalds. Linux is typically package manager, packaged as a Linux distribution (distro), which includes the kernel and supporting system software and library (computing), libraries—most of which are provided by third parties—to create a complete operating system, designed as a clone of Unix and released under the copyleft GPL license. List of Linux distributions, Thousands of Linux distributions exist, many based directly or indirectly on other distributions; popular Linux distributions include Debian, Fedora Linux, Linux Mint, Arch Linux, and Ubuntu, while commercial distributions include Red Hat Enterprise Linux, SUSE Linux Enterprise, and ChromeOS. Linux distributions are frequently used in server platforms. Many Linux distributions use the word "Linux" in their name, but the Free ...

UTF-8
UTF-8 is a character encoding standard used for electronic communication. Defined by the Unicode Standard, the name is derived from ''Unicode Transformation Format 8-bit''. Almost every webpage is transmitted as UTF-8. UTF-8 supports all 1,112,064 valid Unicode code points using a variable-width encoding of one to four one- byte (8-bit) code units. Code points with lower numerical values, which tend to occur more frequently, are encoded using fewer bytes. It was designed for backward compatibility with ASCII: the first 128 characters of Unicode, which correspond one-to-one with ASCII, are encoded using a single byte with the same binary value as ASCII, so that a UTF-8-encoded file using only those characters is identical to an ASCII file. Most software designed for any extended ASCII can read and write UTF-8, and this results in fewer internationalization issues than any alternative text encoding. UTF-8 is dominant for all countries/languages on the internet, with 99% global ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Digi-Key
DigiKey Corporation (formerly written as Digi-Key) is an American electronic components distributor. The company was founded in 1972 by Ronald Stordahl. DigiKey is the fourth largest electronic component distributor in North America and the fifth largest electronic component distributor overall. Stordahl privately owns the company. The name "Digi-Key" is a reference to the "Digi-Keyer Kit," a digital electronic keyer kit that Stordahl developed and marketed to amateur radio enthusiasts. Electrical schematics for the electronic keyer were published in April 1968 by the radio publication QST. History After earning a degree in electrical engineering at the University of Minnesota, Ronald Stordahl returned to his hometown of Thief River Falls, Minnesota, where he took up ham radio in the early 1970s. Stordahl created a kit of electronic parts to improve the transmission of Morse code over his radio. He soon began selling kits to other ham operators, and eventually branched of ...
