Question: What is the round screen shown for the SB2209/2240 Board? #39

On the page for the SB2209/2240 board there's a picture of an LCD screen somehow attached to the CAN port on the board; what screen is this and how does one attach it?

Did you manage to find this thing?

So my closest guess is it might be one of those Waveshare Round Displays, they have both with an RP2040 built in and one that is just SPI, but I'm guessing the SB cover has to be modified a bit to allow for the connector. I haven't found one that would connect to the CAN port but the SPI one could I guess be wired to the SPI connectors. I'll probably keep this as a side project for later (when hopefully there will be something more "official"). Disappointing that @bigtreetech hasn't mentioned anything specifically.

So I've checked a little bit more and it appears that LCD screen is a BTT leak, which was not supposed to be in the SB2209/2240. Latest updates on this: https://www.facebook.com/530918831/videos/194441013221532/

And yes, looks like there will be custom SB cover with special vents for the blower

Oh neat! The sizing looks similar to the waveshare screens just with an ESP32 instead of an RP2040. I wonder if the round LCDs with built in RP2040s would fit the custom piece. Of course now I have to remix my SB cover that already was a remix to accommodate a nozzle cam lol.
