Noob wiring question

[Lytt]

Hey guys, just getting started with drones. I purchased a Flysky Nirvana, which comes with an fs-x8b and an fs-ia8x receiver. And for my drone i got a diatone m540 with the mamba f405 board.

Question is, which receiver should i use, and what pads do i solder to? I have no clue what vcc, ppm, i/sbus, tx6 means. Ive included pics of the receivers and board diagram. Thanks in advance for the help guys!

P.s. are there settings im going to have to change in betaflight for this receiver to work properly?

Here's a wiring diagram but if you're just starting out, you really need to do some research. Download the manual and check out Youtube. There are some great tutorials on how to set up your M540 from start to finish

I think im starting to get it now, i need to wire it to the rx3 on the bottom because its an ibus receiver. But should i wire the power to 5v or to vcc? It says vcc on the receiver board...

Power wires get connected to the 5v and ground beside the rx3 pad
