Looking at my 4” Recon build.. going with a 20x20 stack(Darwin).. the FC’s Uarts are usb vcp-uart1-uart2-softserial1…. In the configurator it shows the SS1 with (vtx-tbs smart audio) already enabled.. I was wondering if I could use this as sbus for the Hd-zero vtx…
Come to think of it… I have to still locate this pad on the FC… just curious as this fc also has a Micro SD slot for black box.. .. I have never used a SS to a uart.. I think I saw Bardwell explain it once…
I pulled the pinout on that fc up.. Darwin has sbus marked clear as day.. just above the rx1-tx1-rx2-tx2 I think I answered my own question ..
