Any information or link to connecting a micro to that transmitter module?

楼主，请问有没有iphone音频输出到tx module的成品转换电路？

If the sensors of iphone could be taken advantage, that would be great. I wonder if we can use this setup to be a FPV headtracker.

Is this similar to the iPhly that came out a while ago?

Yes, we adapt this from iPhly

@George 

Please post the connection diagram.

@Jason, @Max, I believe the wiring would be quite simple. You just need to power the module (Futaba or JR) and send PPM to it's PPM IN. E.g: an FRSky JR module has the following pinout (from top to bottom): PPM IN, N/C, VCC, N/C, GND.

What iPhly originally does is getting the audio from iPhone and using an operational amp chip for outputting a clean digital pulse trail from this amplitude modulated audio. If it were a microprocessor generated PPM signal you wouldn't need any fancy stuff like that. There is just a tricky part easy to deal though: Futaba and some others expect an inverted PPM pulse.

I think it's simple like that. I hope I'm not missing something else. =)

@Max, I found an original post with diagram here: http://bbs.5imx.com/bbs/forum.php?mod=viewthread&tid=710092

Although it is in Chinese, but you can figure out the diagram in attached photos

Hi!

Is it possible to use this app controlling the Newq-bot micro quad from hobbyking - connecting the RF module to the iPhone? Or must I use some kind of adapter..??
