EBAZ4205 Bitcoin miner board -- History

The EBAZ boards are all for brand ebang. Your ebaz 4205 was for a older miner probably less than 10TH. My ebaz (4332) is for the second most latest model, 24TH @ 2600W... but still very old.

The s17+ in comparison does 76TH @ 3000W The latest S21s seem to do around 135TH @ 3000w

Ebang no longer make miners, they just seemed to give up. Many of there machines were faulty and broke, then they quietly left the mining game as though they never even existed... spooky
