Very nice, and that "reconfigurable" part of it isn't something I even thought about, despite the benefits of FPGA technology. Axoloti can do that as well, just in a different way, cause you can save various sketches to an SD card, and select between them using the hardware buttons once Axoloti is in standalone mode, therefore allowing you to completely reconfigure Axoloti on the fly.
No maybe about it, consider it melted mate
That sounds completely awesome, and it's especially comforting to know that it's being designd by someone who works for an FPAA manufacturer. I'd like to second what Jaffa said, please keep us updated on it, just be careful I don't rip your freaking arm off when you finally bring it to market
Of course, what this means in real terms is that once we have the FPAA board, between that and the Axoloti, we'd have a complete Analogue/Digital development system driven completely by a visual building-block interface. Now more than ever, I wish Johannes would release a completely unpopulated version of Axoloti, cause that way it could be connected to your PFAA board using whatever connection design the designer chooses (assuming that your board is unpopulated). If it's going to be populated, then please release an unpopulated version as well, cause being prepopulated with connectors, power jacks, storage mechanisms, leds, switches etc, dramatically lessens the boards viability for bulk commercial purchsers. Some commercial users might accept prepopulation, but the majority won't. It's like with Arduino, they got it right because although the boards are prepopulated, it is extremely easy to "breadboard" an Arduino core and add to it only the parts you need, so you can test a custom board before production.
Try breadboarding an Axoloti core that would work with minimal components
If your board design is prepopulated, it should be easy enough to have some boards made using the same FPAA that you use by following its schematic, so it could be done that way, but again, I think the key for sucess with any product is it's viability in a commercial environment, not just a consumer accessible one, because ultimately, commercial users buy in bulk, and that's not something to take lightly. I doubt the schematic for your board would be too complicated due to being an add-on, but I wish there was a Fritzing-format schematic for both Axoloti and your board when released, cause that would completely work as a professional development system. It means we'd be able to incorporate both the Axoloti and the FPAA into the same board of any design, once the users designs had been worked-out using an actual Axoloti board and your actual FPAA board. In a nutshell, breadboarding a custom PCB is the only alternative if the board isn't available in unpopulated form.
Other than the on-board SD card-holder, USB socket, LED, and Switch, the Teensy 3.6 is s good example of a commercially-viable development board:
It's not completely viable, but from a commercial standpoint it is far more viable than Axoloti, because there is far too much prepopulation on the Axoloti, and very little on the Teensy. There should be a version of Axoloti with the core and all necessary interconnection components, but that is all, absolutely nothing else, not even an LED unless it can be disabled.
So I'm seriously looking forward to your product, but please release it in unpopulated form, or at least relase two versions where one is unpopulated
