Radiomaster R81 wiring to Mateksys F405 TE

Hello,
I am trying to build a drone using the Mateksys flight controller F405-TE and a Radiomaster R81 nano receiver. However, I am not sure how to wire the R81 pins to the F405-TE.
Here is the wiring diagram for the flight controller obtained from Mateksys home page:

Here is the diagram of the receiver:

Should I connect the SBUS of the receiver to pin Tx2 of the flight controller, or should it be somewhere else?
Your help will be appreciated!

Hello,
Sorry to bother with this again.
I received a reply from Mateksys with the following picture:

However, if I look at it correctly, my F405 TE board does not have the Sbus, 4V5 and G pins in this order.
What I have is Rx2, 4v5 ang 5 lined up together.

So I plan to connect here my RadioMaster R81 Receiver.
Do you think there would be any issue??
The pictures in Matek F405 TE Family — Copter documentation are slightly different, so I want to confirm.
Here is the wiring diagram from Mateksys page for the receivers.

Thank you!

For the TE I would go directly to the Sbus pad, not RX2 if you’re just using a regular Sbus receiver.

If you switch to CRSF/ELRS then you’ll want to use RX2/TX2.

All the Matek 405 variants in your link do have Sbus, 4.5v and G pads grouped together somewhere on the board. Even if they’re not together on your particular board you should locate and use the Sbus pad for the Sbus output from your receiver.
