It seems last update on supporting RPI 4 was on 8th of august (about a month ago), so I took a courage to ask if it’s coming out any time soon?
For my project RPI 3 had not enough CPU power, however seems RPI 4 might do the work, so I’m really into trying to finally finish it.
I am currently building version 2.0 which will have less reliance on the RPI for basic operations including PWM control.
But I will need more processing capacity in the future for things like 3D sea floor terrain modelling.
There is no point right now running HTOP because I am in the middle of the build.
However, Version 1 failed because the processing on the RPI in the ocean took the CPU temperature up to 90 degrees Celsius causing the board to throttle. More capacity (plus active cooling for RPI4) is less likely to strain the board.
