I was eyeing the BPI4 for a while, but they stopped making the 8G version, and the 4G version is costing now double of what the 8G cost initially. Thank you RAMpocalypse; but I do not believe a 4G memory module costs 160E, even with the crazy RAM prices. I think banana pi has also switched manufactoring to BPI4 Pro entirely; but 8G is sold out appearantly, and 4G even there is 320E or so.
Which is just really making heavy abuse of the RAMpocalypse really; though I admit; chips are about 50 USD a pop now. insane. Hopefully CXMT can help alive the situation sometime soon.
