Re: Add Analog to Digital pins to the pi

remove composite video , use those pins for analog 10bit inputs add a second power plug to use dual power supply's as the board will get more power hungry as speed of video increases

create a new sensehat for the overheating Pi 4 board with a shield for the extra heat from the Pi 4
