.. I had a nano rx lo longer show any LEDS… can’t remember if I was updating or troubleshooting.. but from what I had read.. if u don’t have ANY LEDs.. it’s toast..
Now at $30 a pop, I still have this HOPING, there is a way to test and confirm..As much as I hated Frsky for their “update”.. along with RXSRs and xm-+s failsafing in front of me.. Forcing my had to go crossfire… (ELRS -had just surfaced)…
Like I said $30 a pop, only one whoop aio with crossfire.. more and more going to ELRS…I’m in the market for a ELRS module..
(Off soapbox)…. Got a bad feeling that it’s toast.. I will be following this thread if u resurrect it and find the fix..

What revision Crossfire Nano RX is it?

Use a magnifying glass to check the board for any obviously missing components. See the post linked to below for more details on the capacitor which most commonly gets knocked off...

Good to know.. and it is near that solder pad.. I’ll check mine when I get home..
