Design Spark

[cropwell]

Sorry Folks, I was a little lacking in specifics (due to frustration!). I was referring to DS PCB. What I am trying to do is create a board with an Arduino Nano module and a couple of 16 channel MUX modules on it. Neither of these exist in the libraries, so I need to create them.

I used to use Circuit Wizard and have produced Gerber files with it that have fed into CopperCam and produced Gcode to mill and drill a PCB. However CW is a dead piece of software and there are no facilities for making library modules.

What I need now is a piece of working (and free) software that will allow me to create the modules I need, incorporate them into a schematic and produce a PCB design for isolation milling and hole drilling.

I have tried TinyCad and rejected it.


Any suggestions ?

BTW Robin, although I work mainly on a Win10 PC, I do have an XP machine to drive my CNC, so, at a push, I could use that.

Cheers,
