I am new to drone building so excuse my questions if I am asking something that is not possible. I have just successfully constructed and flew my drone, so now I am trying to take it to the next level by making it autonomous.
For some background I am currently using the omnibus f4 v5. My drone is set up to use SBUS, has a GPS hooked up to it, and is connected to a 4 in 1 ESC. The software I am using is iNav. My next goal is to wire the 3DR 433 Mhz antennas to a UART, potentially the Rx6 and Tx6 pins. Is this the proper way to communicate with the drone through Mavlink protocal? I intend on using the python kit “dronekit” to control my drone via a computer.
I was also curious if it was possible to connect a servo motor to the flight controller. This servo will give me the capability to drop a package from my drone and I was wondering if I could directly connect it to another one of the UARTS on the board and then just configure it in iNav.
Lastly I also wanted to know if it was possible to use the J8 pins (DSM2 UART1) as a UART for something other than DSM2 communication, or if there was a way to reconfigure the pins via software so I could use them.
