+++ title = "Getting uninverted SBUS on the FrSky XSR receiver" weight = 1 sort_by = "weight" insert_anchor_links = "right" +++ To get uninverted SBUS on the FrSky XSR/X4RS receiver, you can repurpose the CPPM pad. Just solder the following:

Remove the two resistors and solder a small wire from the CPPM pin pad to both (!!!) of the lower resistor solder pads.

Now the CPPM pad will be uninverted SBUS instead.
