Very simple voltage divider for FrSky.
I use 3S battery, so I have maximum 12.6V while FrSky accepts only maximum 3.3V on its analog inputs.
This time without schematic because there is no need to draw two resistors and two connectors:-)
For my case 1/4 voltage divider is just enought. I made it from 1.5k and 4.7k resistors, so with 12.6V on input it will give about 3.05V which is fine for FrSky. I made is as small plug, so I could make connecting cable of any lenght and change it in future without resoldering of divider.
Pictures, pictures 🙂
Just works 🙂
just to be clear: this divider isn’t designed to plug directly into FrSky receiver or battery plug! It will not work that way! It must be plugged to power harness similar to my power splitter and another plug should be used for connection with receiver.
