https://hackaday.io/project/196770-rpi-pico-video4

A RPI Pico RP2040 board with 4 composite video outputs, 8 inputs and switched power

The Pico Video4 Display is a stand-alone RPi Pico RP2040 board, connected through USB-C.
This board provides up to 4 analog composite video display interfaces with integrated frame buffer memory accessible through SPI. The 4 video outputs are accessible through 1 RCA connector and 1 VGA DB15-HD connector that uses the red, green and blue channels for the composite signal.
The heart of this design is the VLSI VS23S040 chip. PAL and NTSC output formats are supported. Currently 4 resolutions are implemented: NTSC 320×200 or 426×200 with 256 colours and PAL 300×240 or 500×240 with 256 colours. The chip has a 1Mbit framebuffer per channel
