One more "crypto mining" FPGA board which will never ROI.
lyra2z is already decimated by bcu1525 and private chinese fpga farms. The last one coin with notable emission GINcoin is forking withing near week or so.
6Mh/s on Phi2 algo earns 5 to 15 cents per day with electricity at 10 cents/KW. Even old cheaply $70-100 rx480/580 Polaris hash the same 6Mh/s on this algorithm.
Lyra2rev3. Current profit is 20 cents per day. This is 5+ years payback period. old cheaply $70 rx470/570 Polaris hash almost the same ~45Mh/s with barely OC and ASM optimized miner.
Tribus, Keccak, 0xbtc, XDAG algos are dead if speaking in terms of profit

No one public available fpga board with a public bitstream can ROI mining cryptocurrencies, especially in current market state.
I want to repeat: mainly only miming hardware manufacturers and hardware resellers earn money in crypto mining  sphere.
Currently crytpomining is a zero-sum game, where miners will always lose, doesn't matter what kind of specialized hardware you are using : ASICs, FPGA.
Take a look at bcu1525, Acorn owners. They all screwed, there are no chance that they'll be able to payback investments even within 3 years period

Please don't call me overly pessimistic. I'm a realist who is familiar with math
