OSD Module board for MAX7456 / AT7456
Datasheet: MAX7456 - https://www.analog.com/media/en/technical-documentation/data-sheets/MAX7456.pdf
This is a breakout board for the Maxim MAX7456 monochrome on-screen display chip. The board is set up with all supporting circuitry and RCA connectors to allow the user to easily interrupt and overlay text and/or graphics onto a video signal (PAL or NTSC).

There are several libraries for this project to work. Library: https://github.com/neomilium/arduino-max7456/
First you need to upload charset into MAX7456 in order to use it.
#include <SPI.h>
#include <max7456.h>
Max7456 osd;
void setup() {
SPI.begin();
osd.init(10);
osd.setDisplayOffsets(60, 18);
osd.setBlinkParams(_8fields, _BT_BT);
osd.activateOSD();
osd.print("Hello world :)", 1, 3);
}
void loop() { }For PCB design i will use services from SeeedFusion.
