Schematics & Layout

You have all the I/O broken out and labeled on the Developer Backpack. Tell me what you are trying to do and I'll tell you how you can do it ;)

hmee.... (so closed HW but open SW)

Backlight pin or is it fixed to VCC?

Yup, there is no backlight control to save so I/O pins... compromises again ^^

Edit: No really closed, because we'll provide what you need. Be we won't put it out publicly to avoid counterfeit and derivatives. Plus some stuff will be public, I just didn't get time to publish it.

Can you post the Layout of the Addon PCB (to create a own addon PCB) and a Pinout (with real port numbers of the M0) 

Obviously! It's planned, as soon as I find the time :)

You'll have all pinouts and a DXF contour of the backpack to be able to make your own that fits perfectly.

I will admit that I was curious about the wiring diagrams, too.

Mostly the part where all of the user pins are open apparently, and I was curious as to how you did that. (as well as just general curiosity. Looking at the classic's diagram was neat)

I can understand, but that is our secret trick against copycats ^__^

and next time you remove the part numbers from the IC's and SMD parts without values on it :D.... or pot it in resine xD

Your true value is in the community and software, not in the PCB Layout...

Yes, that's why we don't need to publish it already, because our only revenue is in the hardware selling.

If you're ready to pay 10€ monthly to use the Gamebuino community then I'll open source the hardware xD

For what is it worth, I've been working on an truly open-source hardware implementation based on the published SDK and emulator. I expect to publish it very soon.

May I ask why ? How did you feel limited by the existing console ? As I told previously, even though we don't publish everything publicly, we'll give you what you need for your project. Also most of the things are not published yet because we simply didn't have time.

Edit: as explained previously, open-sourcing the hardware now would only hurt the Community.

I am a strong believer in open hardware, such as the Arduino Zero that META itself is largely derived from. Anybody who writes code for the META now has no guarantee of future availability of the hardware -- or the ability to build it themselves. That's a pretty serious limitation in my opinion.

You say that open-sourcing the hardware will hurt the community. I say that history suggests the exact opposite and you can find examples of this as far back as the ZX80 computer or as recently as the latest STM32 Arduino derivatives, RepRap, Novena, LimeSDR, PixHawk... The original Gamebuino, which was open, had an FPGA implementation that let you hook it up to a big screen. Did that hurt the community?

With RISC-V CPUs on the horizon, it's about time that the hardware world caught up with software.

has no guarantee of future availability of the hardware

Well everybody that has been around a bit knows that I work very actively on this project, that I'm not here for money, and that if I ever have to stop the project for reasons I'll open source everything. I might even open source in a year or two, but just not right now as it's too early. Arduino was not open hardware right away.

We are not here for profit but money is the fuel that allowed the Gamebuino to be what it is today. I've borrowed 6 figures amounts of money on my own head to change it from a maker project into an industrial product. Don't tell me you can do the same thing in your own garage. Hardware of Gamebuino is just 1% of the thing, we are here to spread curiosity and knowledge. The library and games are open source. We'll give you any info you need about the hardware if you need it for your project.

So if you have any respect for this project, please hold off. And if you still want to open source it, then I'll start taking out the patents. But that's really not how I want it to go.

I've said everything I had about this subject and I will not further debate it. And I know the community is behind me on this matter. Because I care about want people think and want.

The discourse was interesting, but threatening with """patents""" is just lame.
