DarwinFPV Cement Ultra-Durable 5.8G 2.5W Waterproof VTX

Where this data comes from

Read 2026-09-24 off DarwinFPV's own shop. Unlike the 1000 mW Cement beside it this page has no spec block at all - it is prose plus a packing list - so only two fields could be filled. max_power_mw is the brand's own sentence, 'features a powerful 2500mW output, offering strong penetration and stable transmission', restated by the title and by the first feature line ('2500mW High Power Output'); it is output power in milliwatts, and DarwinFPV states no EIRP or dBm figure anywhere on the page. weight_g 21.8 is read at full resolution off the brand's own photograph of the module on a scale (image 5 of 6, a 0.1 g pocket scale with the Chinese unit legend), which is the only weight DarwinFPV publishes for this part; no other unit is physically possible for a part this size. input_voltage is deliberately empty although the case is silkscreened with it: the label reads '7-__V' with the digits hidden behind the connector in the only photograph that shows that face. mount_mm, channels and antenna_connector are empty for want of any statement - the packing list's 'MMCX pigtail antenna (140mm)' describes what is in the box, which is the props' 'for T-mount builds' rule one class over. Stated in prose and not fielded: aluminium CNC housing with an active fan, IP67 to 0.5 m for 30 minutes, two-stage filtering, reverse-polarity/surge/over-temperature protection, SmartAudio.
