Yes, you can use any USB to serial chip to upload programs as long as a bootloader is present. This needs to be flashed with an ISP programmer, such as the USBtinyISP or USBasp.

Is there a schematic drawing available?

Yes, here: https://github.com/MCUdude/MegaCore/tree/master#minimal-setup

Not with MegaCore. You need an ISP programmer to load the bootloader. Then you can use the F232RL to upload new programs.

Is there a resource on how to load the bootloader, can you guide me?

MCUdude commented 11 months ago

There are plenty of resources online. YOu can start by reading the MegaCore readme file. All you need to do is to connect an ISP programmer to the appropriate pins, select your preferred settings in the IDE Tools menu, and hit "Burn bootloader".
