Just a gas but maybe it's because they're using multiple esp32's in an array? But also I seem to recall something similar in the Snowden papers? But I get your point, given that the esp32 and all its design files are available from SPRESIF maybe they built a board that's running out of much faster clock rate? PS: sorry about the typos and miss takes but sadly I have to use Voice typing due to a recent traumatic injury.
