#920 - 13 k16 boards - paid
and orders #918 and #919 were also mine, but paypal was not letting me spend the money so I did a wire transfer on order #920 (I have recieved an email confirmation that funds have cleared).
Since these boards are going to be produced from the bkkcoin designs I chose to order the version that is under development and testing currently. I do not see any plans for the k64 in bkkcoin's github for this project (although once the k16 boards are up and have the communications ready, it should not be that hard to expand).
I think the K64 board is just 4 k16s.
