Hello forum,
It is revealed in (Ted talk) styled promo's for the Pi 5 computer.......... that the CHIP in the top corner (little finger nail size) is a "soul owned design" by the Pi foundation....
....it is an "interfacing chip" and took about 4 or so years to design.
(.........at a total cost of 10 million dollars )
......i hope the above info can help enlighten
thanks
