I've got a SP F7 Dual, and an X8R receiver for my first quad DIY project.
Between these guys, there are a ton of pins, but very little documentation on how to correctly wire them. Most of them seem superfluous, but which, for which use case is unclear to me.
At this point, it seems using the "smart port" on the X8R is the best way forward. According to the SP docs, the receiver port has pin 1 (RXD), 4(+5) and 5(GND) that should be connected to SBUS, and a single pin 3 (TXD/SmartPort) to the data line on the X8R.
Has someone done this, and can you confirm this is correct (see attached pic)?
