+## TT-SC1 settings
+* download software for ADSB TT-SC1 from https://www.aerobits.pl/product/aero/ , file Micro_ADSB_App-vX.XX.X_win_setup.zip and install it
+* connect your ADSB to FC, connect both RX and TX pins
+* in INAV configurator ports TAB set telemetry MAVLINK, and baudrate 115200
+* go to CLI in inav configurator and set serialpassthrough for port you connected ADSB ```serialpassthrough [PORT_YOU_SELECTED - 1] 115200 rxtx``` and close configurator
+* open ADSB program you installed, got to settings and set "telemetry" = MAVLINK,
