Inquiry on PixHawk 6X and Telemetry Radio Differences

Hello,

As I get up to speed with PixHawk 6X, I noticed another device called the Holybro P900 P840 Microhard Telemetry Radio. I’d like to understand the difference between this and the RadioMaster receiver.

From what I’ve read, the key difference is that the RadioMaster serves as an RC receiver for remote control, whereas the Telemetry Radio can communicate back to a base station or computer. Is it simply a computer system executing a function? In what use cases would integrating with a Telemetry Radio be necessary?

Thank you for your help.

Best regards,

Mustafa
