David has said that the X8 is not a plan going forward as it turned out to be too different, and that Frank was looking at something that could be more like the X16. So I think you need not worry about fragmenting the ecosystem in that way. Maybe some other new and improved way, but not that way. ?



I dunno if they have actually abandoned the X8 and dedicated fully to the X16 FPGA. Assuming you are referring to this screenshot from Facebook:

tl;dr: "Huh, yeah, the X8 was an interesting proof of concept, even if they decided not to release it to the market."



 



I even made a conceptual PCB Front for the X8 hoping it would be released. just to be clear, I did this in MSPAINT.

Yup, I was relieved to see that.  I was about to say I'm still a little skeptical that that's actually what he meant based on the wording in the screenshot that's been circulating, but I did some searching on the Facebook group just now, and apparently they've come to the same conclusion, and I'm sure they would have been corrected by David or Frank there if it wasn't true (since they both seem to regularly post there).



Don't get me wrong, the X8 does sound cool, and I would probably buy one at some point, but I'd just feel better if the X16 came out first.



Same. Whatever hardware they can get out the sooner the better.

So what else can we talk about that is not this topic and not off-topic?  {crickets}



 



I think its really cool that Frank used STM32F7 MCU in the design to act as a programmer for the ICE40UP5k FPGA. Really clever design. I used STM32F7 MCU's in my racing drones but it is still really cool seeing it used this way. 

Major Components from BOM:

U1 FPGA: ICE40UP5K-SG48ITR50

U2 Flash - NOR Memory IC (16MB): W25Q16JVSNIQ 

U3 LDO Voltage Regulator (1.2A): LDL1117S33R

U4 LDO Voltage Regulator (250mA)

U5 Microcontroller: STM32F070C6Tx

U6 Wireless Module (802.11 b/g/n): ESP32-SOLO-1

X1 Standard Clock Oscillators: SG-5032CAN

Y1 SMD GLASS CRYSTAL: 7A-8.000MAAE-T

Exactly. You have to recognize genius when you see it. The VERA / X8 FPGA is an incredible work of art by @Frank van den Hoef. What an excellent gift to the community.

Yes, there is nothing there that pins down what will be done, just saying what isn't going to be done and what the next step is going to be as they work out what to do.

So, nothing there suggests are implies looking at a "more compatible" "X8 style" design later ... but nothing specifically excludes it, either. It's just one piece of the puzzle in place ... not going ahead with the X8 prototype as designed ... and a mention of what the next step of work may be as they sort out how they are going to proceed.

And that's the frustrating bit when i comes to deciphering what's next. We don't know if they decided to completely abandon the X8 but it seems like the end goal is the X16 FPGA. Regardless it seems clear that we can expect an FPGA solution before the chip & dip

What I am saying: just take the actual piece of information. Don't go spinning off into speculation not supported by available facts. There are no facts that warrant supposing that we can expect a "new X8" or an X16e before an X16p.

Now, if they had a definite plan, they'd announce it. So development work without a definite plan is quite plausibly going ahead in order to find something out which is not necessarily clear until an actual working prototype is available.

Proceeding with the (long planned) X16e design could be to sort out hesitation on scrapping it just as much as it is to settle hesitation on going ahead with it. Barring word from the development team, supposing it is one or the other is just guesswork.

Indeed, it's just as plausible to have a joint X16e / X16p DIY crowdfund or pre-order campaign, since that would make it easier for the first campaign to hit a target of 1,000+ keyboards in the first keyboard order.

Bruce, with the different tiers “P,E,C” I honestly don’t know what’s what anymore. I dunno which X16 variant ties to the Chip & Dip but it’s pretty clear what the Chip & Dip is vs the FPGA.

They haven't changed. X16p, "pro", aka "Plenty of chips", is the one you have been calling chiP and diP, X16c is the Cost reduced one, the X16e is the one with the processor core Embedded in the FPGA.

Mostly FPGA first, Mostly FPGA alongside the X16p, and Mostly FPGA after the X16p ... aka X16e, first, alongside and after ... are all quite plausible at this point.

Just "the FPGA" is a bit confusing since all three will have Vera in an FPGA, it's just the X16e will have more stuff in there alongside.
