CVP-13 | FPGA Runs under Windows 10 for Zetheron algos (X16R, Nexus, 0xToken, and more) or Linux
Uses off-the-shelf liquid coolingyou provide the loop and hook up to CVP-13s supplied water block
Compatible with PCIe risers; with Zetheron algos USB+Power is all thats needed (no PCIe at all!)
Active FPGA Discord community; walkthrough videos/guides for setup
The Most Versatile Miner for Ravencoin
Support for RVNv2 is coming soon from Zetheron, with a target of 240 MH/s from a single CVP-13! More than that, CVP-13's versatility means that future forks of RVN will be quickly adapted to this board.

It turns out that changing algorithm on the last fork does not protect against FPGA...On the face of manipulation, not only with the price of rvn, but also possible preferences to one of the equipment manufacturers...

They never tried to get rid of fpgas only Asics that's why they added algo for Wich there were bitstreams for 2-3 years already

You are correct that the goal was to get rid of ASICs, not FPGAs. However, I don't know that I buy that this "CVP-13" is an FPGA. Sure it can handle several mining algorithms, but it appears to be an integrated circuit designed specifically for the application of running mining.

Irrespective of whether it is an ASIC or an FPGA, the net result is the same. Their website clam 3 CVP-13's can run on a machine at 1600W for 720h/s. That's the same power as it takes to run 6 1080TIs (200 H/s).

1080TI mining is simply not feasible right now (I stopped in October of last year after hitting my 50k Raven goal). The net hash rate has more than doubled and even the numbers put out by the FPGA are unimpressive.

3 CVP-13's cost ~$16500 + 500 for other computer parts for a $17k investment vs. 6 1080 TI's + computer ($5000 less if you roll the dice on used)

Assuming $0.10/kWh for power:

Today the 1080 TI machine makes $1.28/day mining GRIN = 3906.25 days to pay itself off (10.7 yrs)
Today the 3 CVP-13 machine makes $2.23/day mining RVN = 7623.32 days to pay itself off (20.9 years)

So if we agree that CVP-13 is a permissible FPGA, and we assume that they can mass produce it to double the net hash rate of Raven in 3 months, people have been investing that strongly in this device to reap a reward 21 years from now?

The numbers don't lie, and miners would have to be extraordinarily stupid to investing that many resources in FPGAs for Ravencoin with so distant a payout. There are ASICS out there, and they likely have much better numbers than this CVP-13 "FPGA"
