I am building my first quadcopter, having salvaged the FlySky ia10 ppm receiver and FlySky i6 transmitter from my old Flying 3D x8 quadcopter.
I have two questions:
1. Can I send back battery voltage data back to my transmitter through Naze32?
2. Does the front arrow of the Naze32 board have to point absolutely forward or a little deviation is allowed?

Note: My previous quadcopter could send back telemetry data through the transmitter/receiver setup.

Firstly, welcome to the forum.
Not sure if the FlySky i6 transmitter supports Telemetry, so will let someone else chime in.
The naze32 can be mounted 90, 180 or 270 degrees according to how you set it up in the GUI.

Ashim.

Flysky i6 transmitter supports telemetry. It shows rx voltage. But if you want to measure some other parameters we need to have specific sensors for every individual parameter.

Yes, this is specifically what I want. How do I connect the receiver to the Naze32 for monitoring battery voltage?
