I'm trying to use a 2.4 GHz digital 6 channel remote controller to send signals to an Arduino UNO R3 board. The receiver is the HK-TR6A-V2.
I can't find any information on what each pin input/output is, and how the information is encoded. Since there are 3 pins for each of the 6 channels, I imagine that each channel has its own Vcc and ground, and the signal itself will be on the third pin, but I'm not sure which is which.
Also, I don't know what voltage should be supplied to the battery pins (and why there are 3 pins for the battery).
The modulation used to encode the signal in each channel seems to be PPM, but I'm also not sure about that.
Has anyone worked with this receiver (or a similar one)? Is there a manual or any information about how to interface it with an Arduino board?
