Nobody has written firmware for this board. This is fluidbox's own C, compiled against that board's own device.json through packs/web and run at its panel size with its buttons, and it proves exactly that much: no driver, no timing, no memory pressure, no silicon. fluidbox on M5Stack CoreS3 (silhouette): degraded. It runs at 60 particles against the reference 130 (how many particles the fluid is made of), bound by panel area (320x240 at one per 1268 px). This target is unverified against silicon, so every number above came from a datasheet, not from a board. A verdict is a comparison of two documents, never a prediction that the port runs.
