Hello :)

This ended now in prototyping and building a showcase. It was not my intention and I could not completely foresee, that it would fit that well.. I mean the whole outcome:

It is ALL pin out, really all! I could easily solder the remaining probe connections to the lower row to make it complete and I would bring GP1 as high freq input to the outside.

It is very robust and compact and offers everything I can think of. The audio could be replaced by a I2S, the space is sufficient. The PGA2350 is a great design for me.

All kind of firmwares available for 2350 can be used and make sense and is suitable for almost every interest.

This is again dedicated to us all. Take one or the other idea maybe and I hope again that I could give some inspiration. It was also my way trying to contribute..

All the best to All of you!

Just a concept and it's all about the form factor and versatility.
I've seen now all work from everybody.

It's an old keyboard for oldschool pads but feels like a lenovo. I will make it completely foldable.
I took the time and made it work in full extend and the audio sounds and works superb!!

Cheers!

great
