TTL to USB / SBUS to USB / SBUS to TTL converter

Overview

Introduction:
I noticed that the ones sold online were rather ugly, and since I was using fewer and fewer modules, I drew a simpler and nicer
functional diagram .
Figure 1 shows an inverter, which can also be used as the "Black Sheep Mod" in a racing game.
Figure 2 shows a USB to S-Bus converter; the S-Bus can be detached and used separately, resulting in a TTL to S-Bus converter and a TTL to USB converter.
Figure 3 shows a USB to TTL circuit.
The DIY
BOM cost is only a dollar or two.

Bluetooth Protocol
I was also looking for Bluetooth protocols some time ago. I found some of them, but they seemed very difficult and I slowly digested them.
I encountered a problem when testing the CAN communication isolation chip a few days ago. I hope you can give me some advice.
The question is quite long, so I wrote it in the Word attachment, and also attached the chip specification. I think it might be caused by the incorrect input level range of CAN communication.
