the other board (40x40 mm one) i mentioned was much harder to get, it’s only sold somewhere in china, and i only ended up getting it bc some guy messaged me on the forums and offered to buy an additional one and post it to me, and it took 4 months to get to me

(but it’s a earlier prototype, very little ram, so you’d probably want the one in the pic related)
