Connect OAK-1 to cheap small LCD display

Hi,

I would like to connect the OAK-1 to a cheap microcontroller that can be connected to a small display (let’s say 7" LCD).
the purpose it show the on the LCD the live video stream of the OAK-1 plus the YOLO classification bounding box.

I know that one alternative is connecting the OAK to a raspberry pi with a display, but it would cost around 70$. I am looking for a much cheaper alternative

do you have any recommendation?

thanks
