Defines if you are using TBS SmartAudio or IRC Tramp.
Newer VTXs use SmartAudio 2.1+ (power in dB), while older ones use 2.0 (power in 0-3 values). vtx-tables
Defines available power output, mapping mW (e.g., 25, 200, 800) to dB values. Why You Need Them Defines if you are using TBS SmartAudio or IRC Tramp
are a crucial configuration file in Betaflight (since version 4.1) that tell your flight controller exactly how to communicate with your Video Transmitter (VTX). They map specific frequency channels and power levels (mW) to commands sent via protocols like SmartAudio or IRC Tramp . Key Components of VTX Tables Why You Need Them are a crucial configuration
