I am planning to design and build a 3D printed RC Airplane.<\/strong> To shortcut the “Remote Control” functionality I bought a second hand Spectrum DX 6i <\/strong><\/a>that I wanted to use together with a Spektrum Satellite Receiver<\/strong>: These Receiver Boards are quite small<\/strong> and it should be quite easy to use them together with an Arduino<\/strong> compatible board that uses a 3.3V logic. The Spektrum Satellites uses a serial data line.which can be read from the Arduino RX port.<\/p>\n

\"\"<\/p>\n

So I purchased 2 “Satellites” and so far I have written a library<\/strong> which implements the binding and data receiving. But I just don’t manage to put these receivers to bind with my Remote<\/strong>!:<\/p>\n

I started off by using some cables that I have bought on the internet and I might have fried one of the receivers this way: It seems that for the cables it is not defined in which sequence you have the +, the – and the Signal cables. I just plugged in my cable and connected it to a ESP32 using the colour of the cables without double checking!<\/p>\n

It took me quite some time to notice that the sequence of the colours was wrong on my cable! By looking at the Satellite Spec\u00a0<\/a>I finally managed to get it right:<\/p>\n
