The unit speaks TBS SmartAudio over a single UART TX pad on your flight controller. Once wired and enabled in Betaflight or INAV, you can switch band, channel, and power from the OSD without landing the model.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eQ: Can I power it directly from a 6S or 8S battery?\u003c\/strong\u003e\u003cbr\u003e\nA: Yes. Input range is 7–36 V, so 2S (≈7.4 V) through 8S (≈33.6 V fully charged) packs feed it directly. For 8S HV LiPo where full charge may exceed 36 V, use a standard (non-HV) 8S pack or add a step-down regulator.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eQ: Will it fit a standard FC stack?\u003c\/strong\u003e\u003cbr\u003e\nA: Yes. The 30.5 × 30.5 mm bolt pattern matches the most common full-size flight controller \/ ESC stack. It does not natively fit 20 × 20 mm micro stacks.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eQ: Is the LOW band legal in my country?\u003c\/strong\u003e\u003cbr\u003e\nA: The LOW band (5362–5621 MHz) overlaps with frequencies not authorized for unlicensed operation in many regions including the US (FCC) and Canada (ISED). Compliance is the operator's responsibility. North American pilots typically operate on Raceband, F (FS\/IRC) band, or specific A \/ B \/ E band channels.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eQ: Does it have a built-in microphone?\u003c\/strong\u003e\u003cbr\u003e\nA: No. The VT5804 transmits CVBS video only. For on-aircraft audio, use an FPV camera with an integrated microphone, or add an external microphone module between the camera and VTX.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eQ: Does it support IRC Tramp protocol?\u003c\/strong\u003e\u003cbr\u003e\nA: No — TBS SmartAudio only.
