Build Log Wiring up the Afromini to the microFrx





The Afromini can use the ppm output of a microfrx. The pinouts are as the attached image.



In text, its:

FRX AFROMINI

PPM -> PPM

3v3 -> VREG Power

GND -> GND on PPM Channel



I am having trouble getting the microfrx to bind at the moment, and the second image shows that I have gone from using tweezers to short, to using a small blob of solder to conduct.



What I have done:

Set Taranis to D8 Mode, and scrolled down to set Bind on. While bind is on, the taranis emits a bird chirp. The Red Microfrx led should go from solid red to blinking Red... as of yet it's not. :/



Just tried having bind mode on the taranis set before powering up the Flight Control board and MicroFrx, as well as engaging it after, but that did not make a difference.



Addendum:

It was a faulty MicroFRX. I had a spare one I was going to use for another project (the beefys brushed board one), and tried it. Worked first go, hooray! I even got to map channels correctly.



The trick for it was to power it up, with the bind pins shorted. The Taranis needs to be in bind mode, like I wrote above. What will happen is the red led should do a few (I saw two) short blinks, then slow consistent blinks. You can then power off and on your Transmitter.



You should notice the intensity of the Red LED intensity should change, when the transmitter is on (to be brighter).



With that done, make sure enable PPM input is on in baseflights configuration Tab, and you can then see if the receiver is changing inputs based on you moving the stick!



I noticed right away that it's set up for what looks like a default of mode 2. This might be my Taranis though (I am Mode 1) Inbetween steps from this guide , so....The Afromini can use the ppm output of a microfrx.
