Easyeda boardRs485 control 3 camera, L298 2 motor, 3 strip led,

I need a complete Easyeda (mandatory) project with:

Powered with 24v
1) Arduino nano ( 2 x16 pin female headers to put arduino nano on it) powered on vin with 7v
2) MAX485 ( correct wired to arduino)
3) L298 to control 2 motors at 12v
4) 3 12v strip led control (switched by my arduino code. Example i made it with a CD4066)
5) 3 composite camera switch
6) PCB will have a screw terminal block with 6 pin ordere as :



This board will receive rs485 command to:
- switch between 1/2/3 led strip
- switch between 1/2/3 composite camera

And exit signal on 6 pin screw terminal block:
1 24V+ (IN)
2 GND
3 RS485/A (IN)
4 RS485/B (IN)
5 Camera out (OUT - selected from the 3 cameras)
6 Camera gnd
Pls ask 2+3?

I need : schematic, pcb and bom.
All ready to send to easypcb to make and assemble it.
