I just received a couple.
A teensy 3.6 can run 2 of them chained if you really want to, but the refresh rate is truly terrible
It was easier to run them as 128x64.
They work with SMARTMATRIX_HUB75_64ROW_MOD32SCAN except that they also use those new FM6126A chips, so they don’t even light up unless you send them the magic reset string, and even then I had to send it multiple times for it to go 128 wide and finally allow the whole panel to light up (or I was missing columns as the later shifters weren’t working).
Even then, I still have the problem where the top half and bottom half of the panel look different:
(for reference a P4 64x32 panel and a P3 64x64 panel on the side)
Still, cool panels to get so many pixels in such a small form factor.
The downside is that the pixels are super fragile and some corner ones fell off as soon as I unpacked the panel
