Where this data comes from

Happymodel's product post prints the block: Output power: 25~200mw switchable, Frequency: 40CH, Input voltage: 4.8v~5.5v, Current consumption: 250mA~510mA(type), Antenna: RG178 antenna U.FL interface, Frequency: 5.8GHz 5bands 40 channels, With Raceband, Smartaudio ready, Weight: 3g without antenna, plus the recorder rows: Video Output Size VGA (640x480), Video Output format NTSC, Record video size 1280x720 @25FPS, TF Card support Max.32G, Compress Format AVI. power_levels_mw is the manual's own instruction - "set vtx_power=1" is 25mw, "=2" 100mw, "=3" 200mw - and that manual prints the same 5-band 40-channel table (Band1 5865-5725, Band5 5658-5917 MHz). A transmitter that records to its own TF card on the VTX board rather than in the goggles; recording starts automatically at power-on and the manual warns there is no auto-save at power-off.
