There is no non-wireless version of the Zero 2 (at least as far as I'm aware). The board OP posted has never been available for purchase for $7. Even the 32 bit armv6l predecessor cost $10 at launch And either way, as my previous post points out, the Amazon price history has never dipped below $40.
