Just got those today for some 128x64 panels, they don’t work at all with anything.
Yet another incompatible chip
opened 11:22PM - 19 May 20 UTC
I ordered 4 panels, and to my surprise they didn't come with FM6126A chips, they… have some ICN2053BP chips I haven't seen before (normally they're ICN2028BP)
So far, haven't been able to get them to turn on, with or without the FM6126A string.
It's kind of vexing that those chips keep on changing in incompatible ways :(

I don’t expect support, just throwing this here in case someone ends up stuck with some.

@Louis you may be interested in the latest reply on that bug that says that apparently this new chip can actually receive values to display and do PWM on its own.
If so, finally? why did it take so long?
