Functional Control Relay
As a first order of business, I assembled the basic relay as the last part arrived right before the end of last term.
The PPM output of the FrSky X4R was input into the DJT module’s PPM in. Using a forum post, I determined the pinout of the module. The DJT module doesn’t have listed power specs, but I took an educated guess and powered it with 5v, which seemed to do the trick.
I tested the system using a servo plugged into the “end” receiver and it worked as expected!
