https://www.adiuvoengineering.com/post/first-look-xilinx-kria-soms (https://www.adiuvoengineering.com/post/first-look-xilinx-kria-soms)
Custom-built XCK26 (close to ZU5CG), 4GB, 16 GB eMMC and all other Zynq UltraScale+ goodies (USB3.0, PCIe, GTR, etc). Two 240-pin connectors, so hopefully all the IO we will ever need.
Kria KV260 Kit: $200 (includes the commercial SoM)
Kria K26 SoM: $250/$350
Datasheet: https://www.xilinx.com/support/documentation/data_sheets/ds987-k26-som.pdf (https://www.xilinx.com/support/documentation/data_sheets/ds987-k26-som.pdf)
Do we even get any Zynq Ultrascale+ ICs on Digikey/Mouser whatever for less than $200? So I wonder why such aggressive pricing (for Xilinx) here.
More interesting: Roadmap also shows a cost-optimised SoM, likely based on ZU1? Too optimistic to hope for $100? Cmon Xilinx, cannibalize the older Zynq already.

Actually closer to the ZU5EV (K26 datasheet says it includes the codec). Pretty remarkable for the price. The SOM vendors are not going to be happy (i.e. Trenz TE0803-04-5DI21-A is $1400).
-
Yea, I've received an email from Xilinx about it as well. Sounds pretty interesting. Will wait for it to become available at the likes of Mouser, and will buy a kit to play around with.
-
That's a really nice FPGA for the price, wow
-
Digikey/Avnet/etc. price are not real prices. Maybe if you buy few (like < 10 ) per year or only one shot.
If you buy 1000-5000 qty per year, you can divide distributor price by 8-10 to get a "real" price idea (still rough though)
This SoM is clearly an answer to Nvidia's Jetson. Professionally speaking, it's even more interesting than Jetson on some points.

Xilinx is doing it again?
Here in China there was a time when the cheapest dual-core Cortex-A9 chip from any western brand was Xilinx Zynq 7010, and there are some bitcoin mining rigs that uses that chip purely for its CPU (and left its FPGA barely touched.)
-
It seems the kit will available not early than at end of the year on Mouser/DK.
If you will go directly, might cut a few months off.

By today's standards, the end of the year is very early :)

There are some Kria KV260 development kits available right now on Digi-Key for those of you who might be interested! I already snagged one for myself >:D
https://www.digikey.com/en/products/detail/xilinx-inc/SK-KV260-G/13985269 (https://www.digikey.com/en/products/detail/xilinx-inc/SK-KV260-G/13985269) Already sold out!
There are also some coming soon to Mouser:

The SoM is available on Mouser although a bit pricey

I'm waiting for this accessories kit to be available to buy them both: https://www.digikey.ca/en/products/detail/xilinx-inc/HW-BACCP01-SK-G/14111914?s=N4IgTCBcDaIEIEEDCSAKAGAjCAugXyA (https://www.digikey.ca/en/products/detail/xilinx-inc/HW-BACCP01-SK-G/14111914?s=N4IgTCBcDaIEIEEDCSAKAGAjCAugXyA)

I looked into the accessories. It's just an Ethernet cable, a micro-usb, an HDMI, a power cord, an empty 16gb flash card, and a raspberry pi cam 2. Nothing special that you can't source yourself for probably a lot less money. The power supply is 12V@3A with a barrel jack
-
I wonder how difficult it would be to attach SATA and Ethernet to this SoM.

Not that difficult I presume as PS MGTs support SATA3, but you will need to design your own baseboard and use off-the-shelf SoM (because as I understand the kit comes with SoM permanently attached).

That's really good, but I wonder how much extra circuitry it needs?

You will need to provide power to your SATA device, but aside from that, there is not much required aside from the usual baseboard stuff. I don't remember if Xilinx published schematics of the kit's baseboard, if they did, you can refer to it to see what's involved.

Looks like it's not soldered to the base board.

However, the SoM in the kit has one of the connectors to the baseboard unpopulated.
See https://youtu.be/h87n2Pj_Q78 (https://youtu.be/h87n2Pj_Q78) at the 10 minute mark.

31 more units available on Mouser, get em while they last!
