The circuit is connected between usb2ttl and mcu. If not for hobbies, I would recommend you buying them instead of making them, which is quite time-wasting. Search "Automatic Download Line STC MCU 51 Program From USB to TTL Without Manual Cold Boot", you can find those usb dongles.

If you have interests, I once wrote a blog (in Chinese) about this circuit, you can find it at this link. Open it in Chrome then it can translate it to English. I attached the full schematics and the final pcb in that blog.
