BetaFPV A02 25-800mW 5.8G VTX

Of the 81 other 5.8 GHz analog video transmitters in our database, 30 have a lower maximum power than the A02 25-800mW 5.8G VTX (800 mW, 29 dBm), 12 the same and 39 a higher one; the class median is 800 mW. The A02 25-800mW 5.8G VTX steps through 25 / 200 / 500 / 800 mW, which is 14 / 23 / 27 / 29 dBm: the top level is 15 dB above the lowest, about 5.7x the free-space range on the same antennas.

BetaFPV's own Betaflight VTX table is on this page: 5 bands of 8 channels, 5645–5945 MHz, 4 power levels, SmartAudio 2.0. CLI commands and JSON file.

Source: https://support.betafpv.com/hc/article_attachments/4410935832089 — Copied from the maker's Betaflight CLI file A02.txt attached to the BETAFPV support article 'CLI for VTX' (https://support.betafpv.com/hc/en-us/articles/4410949062809-CLI-for-VTX), which the product page links. The file's header says SmartAudio 2.0, so the power values 0-3 are level indexes, labelled 25/200/500/800 - the page's 25/200/500/800mW. All five bands are marked FACTORY.

Transmitting is only legal on the frequencies and power your country allows; see VTX frequency bands.

Where this data comes from

BetaFPV's product page prints the labelled block: Output power: 25/200/500/800mW (adjustable), Supply voltage range: 7-35V, Weight: 5.26g (excluding antenna), VTX size: 27.3x27.3x4.5mm, Antenna: Air Antenna(MMCX Straight), Frequency: 5.8GHz 48 channels, with Raceband: 5658~5917MHz, Channel SEL: SmartAudio, Channel Indicate: 3 LEDs. The scale photograph reads 5.26 g, and the pinout drawing labels the connector ANT(MMCX). channels is EMPTY although the block says 48: the page's own channel table is five bands of eight (A, B, E, F, R) and prints no L band, so the brand states 48 and 40 for one radio and this column publishes neither - the same test the mounting pattern gets elsewhere. mount_mm is not in the block at all; it is the brand's own dimension drawing, which measures 26mm x 26mm between hole centres, the banner reading '26*26mm Mounting Hole', and the comparison table on the A03's page, which lists the A02 at 26*26mm. A built-in microphone is part of this board and has no column here.
