A cross platform and open source electronics design automation suite, KiCad EDA includes schematic capture, PCB layout, and a 3D viewer for electronics engineers. Create designs without limit, make professional PCB layouts, and inspect designs in an interactive canvas with KiCad EDA.
Key Features:
Up to 32 copper layers
Lay out boards more quickly
Draw your track while KiCad pushes forward traces that are in the way or reroutes tracks around obstacles
Push and shove router makes sure your DRC constraints are respected
Footprint editor (GAL)
Schematic capture is efficient, with all the tools you can expect for such a task. The interface focuses on productivity. There are no complexity limits, as large designs can be divided into hierarchical subsheets. Various export options are available (PDF, SVG, HPGL, Postscript).
PCB Layout
Make professional PCB layouts with up to 32 copper layers. KiCad now has a push and shove router which is capable of routing differential pairs and interactively tuning trace lengths.
KiCad includes a 3D viewer which you can use to inspect your design in an interactive canvas. You can rotate and pan around to inspect details that are difficult to inspect on a 2D view. Multiple rendering options allow you to modify the aesthetic appearance of the board or to hide and show features for easier inspection.
