TTLinker_mini_half duplex asynchronous serial bus communication

Hi
i want to make a project that uses some servos (SCS 15 Feetech)
They use a half duplex asynchronous serial bus communication.

I used a special module (TTLinker_mini) to drive them but recently i discovered that they stopped import them and are not available any more.

in a pdf manual for this type of servo there is a schematic to make your own half duplex asynchronous serial bus communication

So i am thinking to design my own pcb that will include that but the schematic is not clear.
some part number are not visible / clear

Here is the link for the pdf manual : https://grobotronics.com/images/companies/1/datasheets/SCS15&SCS115%20Manual.pdf?1516269264467

Any one that can recognize the parts? or any other suggestion will be welcomed

Why don't you use Zihatec RS485 shield for Arduino UNO with galvanic isolation for professional use?
