CadSoft EAGLE Layout Editor

The EAGLE Layout Editor is an easy to use, yet powerful tool for designing printed circuit boards (PCBs). EAGLE offers the three modules: Schematic-Editor, Layout Editor and Autorouter embedded on one single interface.

CadSoft EAGLE Layout Editor

EAGLE is easy to learn, easy to use and easy to buy. It runs on Linux, Mac and Windows and allows feature enhancement, such as simulation, 3D-visualization, data import and export and self defined commands, through User Language Programs (ULP’s) which are partly integrated in EAGLE 

The name EAGLE is an acronym, which stands for .

Easily Applicable Graphical Layout Editor.

The program consists of three main modules, Layout Editor, Schematic Editor and Autorouter. These are embedded in a single user interface. Therefore there is no need for converting netlists between schematics and layouts.

gEDA Project - Electronic Design Automation tools

The gEDA project has produced and continues working on a full GPL'd suite of Electronic Design Automation tools. These tools are used for electrical circuit design, schematic capture, simulation, prototyping, and production. Currently, the gEDA project offers a mature suite of free software applications for electronics design, including schematic capture, attribute management, bill of materials (BOM) generation, netlisting into over 20 netlist formats, analog and digital simulation, and printed circuit board (PCB) layout.

gEDA Project - Electronic Design Automation tools
 
The gEDA project was started because of the lack of free EDA tools for UNIX. The tools are being developed mainly on GNU/Linux machines, but considerable effort is being made to make sure that gEDA runs on other UNIX variants. For a complete list of freely available tools please be sure to visit Open Collector.

The Micro Stop - RS232 microcontroller schematics

"These pages are a useful collection of microcontroller RS-232 data acquisition circuits and code. Most of the code on these pages is written in C because it is the language that is definitely the fastest way to produce working applications."

The Micro Stop - RS232 microcontroller schematics

DVM-001 voltmeter kit

RS232 controlled and RS232 powered DVM-001 voltmeter kit with PC voltage display. This circuit uses a PIC12F675 8-pin microcontroller with built-in analog to digital converter. The circuit also has an op amp and resistor divider network to achieve the 54vdc max input voltage.

RS232 serial tools

This  rs232 data monitor is a thoroughly field tested and reliable software tool for serial monitoring, troubleshooting and logging rs232 communication. A laptop PC and this com port monitor give you a powerful, portable and sturdy tool to aid in designing and logging rs232 data between peripherals and hosts.
