FPV Drone Remote Control Receiver XK-ELRS 915M

Transmitter compatibility
This receiver can be used to frequency different brands of high frequency heads. The ELRS project is an open source project, so as long as the high-frequency headers of the ELRS protocol are used, regardless of the brand, they can be linked to each other, but three conditions must be met:
1. The frequency should be the same, the same is 2.4G or the same 915Mhz, etc
2. There are three types of firmware version certification standards: AU, EU, and FCC. To be consistent, for example, the high-frequency head flashes the FCC 3.0.0 firmware, then the receiver should also flash the FCC 3.0.0 firmware or above;
3. None of them have a linking password, or they all have the same password.
