Hey, I’ve connected my rfd900x to pixhawk 3 pro at telem 1. The connection works just fine when I power my pixhawk from USB (connected to my computer). But, when I power the quad with a lipo, the rfd900x shows a flickering orange led, momentarily, and then no light or any indication that its’ powered on. All my other sensors/accessories (gps, rx, etc) are functioning normally.
So it seems as if the USB provides sufficient power to telem1 to run the rfd900x but not the lipo / power module (Mauch PM). Any suggestions or ideas?
Unless someone has a solution, I’ll try to power the rfd900x with a separate 5v bec and connect only TX/RX and CTS/RTS between radio and pixhawk. That may work just fine but its’ an added complication that I’d hoped to avoid… Thanks!
