@ Jeff : there are many reasons for me to use this board :
- I got it before the Wiznet driver was completely usable
- I have it and I don’t have the WizNet board
- most important feature, for me : the Moxa board can act as a virtual COM port for Windows, a feature very useful for almost all the programs I’m currently using.
- it can use using only 2 pins for serial communication (Domino <-> Moxa)
- not really important but still : it also exposes 4 programmables IOs. That saves 4 on the Domino, for example.
- less important, it already has some little “plus” like email alerts on different conditions
@ Sam : in fact, I don’t have “time” to learn something almost new for me Altough some years ago, I have used Proteus PCB Design for a small board (see below). But I don’t have access to this program anymore, hence my request about Eagle.
The proto boards you mention don’t really fit my needs because they have many “features” that I don’t need like rails or SOIC. This take some useful space. Also, Moxa pinout is not really suitable for use with this kind of breadboard.
That’s why I think that a custom PCB would be better : only the components I really need and components specifical to this module (IOs, for example).
Waht do you mean when you say ? [quote]you need to test your board first before step into do the shield with eagle.[/quote]
Anyway, I thank you for your answers.
Oh, I still have a question : how much current can the 5V pin on the Domino draw ? The Moxa is using 300mA in idle state and is said to go to 900mA on load (though I haven’t seen this high value yet :think: )
This would change the way I power the board, of course.
Here are some pictures of a board I’ve made with Proteus PCB Design :
And the final real board :
