Rakefile to manage hardware projects
|

|
||||
uses Lepton EDA for schematic and pcb-rnd for board layouts.
|
||||
uses following tools:
|
||||
- QEDA https://github.com/qeda/qeda
|
||||
- PcbDraw https://github.com/yaqwsx/PcbDraw
|
||||
- KiKit https://github.com/yaqwsx/KiKit
|
||||
- KiAuto https://github.com/INTI-CMNB/KiAuto
|
||||
- KiBoM https://github.com/SchrodingersGat/KiBoM
|
||||
|
||||
Rakefile instead of Makefile for better text file parsing capabilities.
