Passive A/V example circuit for Raspberry Pi 500
This simple circuit demonstrates composite video and audio out from Raspberry Pi 5 series computers, using only passive components (it cannot produce composite video from Raspberry Pi 400 or earlier models). Audio quality is limited: some power supply noise may be audible. The circuit is nevertheless useful for less-demanding applications.
This is not an official product. It has not undergone regulatory testing. But you can make and adapt it.
