Where this data comes from
Second source 2026-09-23: HDZero's own product page prints the labelled block the retail listing paraphrases - Model HDZero Race V3, SKU HDZ3143, Frequency 5.725-5.850GHz, Resolution Default 540p90/720p60/1080p30, RF power 25mw/200mw, RF Connector Secured U.FL, Interface 4 lane MIPI CSI YUV422, Size 32mm x 28mm x 5mm, Weight 5.5g, Harness length 40mm, power input 4V-12V, Mounting 20mm x 20mm M4 with rubber grommets. It confirms the 200 mW, the 5.5 g and the 5.725-5.850 GHz already published and adds the two power steps and the input range. mount_mm gains the screw size: the holes are M4 and the included 'Rubber Grommet (M4 to M3)' reduces them to M3 screws, which is why the HDZero VTX User Manual v1.1 (linked from hd-zero.com/document), p2 'HDZero VTX Products' table prints the same pattern as '20x20 M3 (Soft)' - the table names the screw that goes through the grommet, the product page names the hole. channels is the manual's 'All VTXes support R1-R8, E1, F1, F2 and F4 channels' (p8); L1-L8 exist only after the low-band unlock firmware. power_draw is the maker's own supply figure, 'Power Consumption: 5~6W' in the Race V3 column, read 2026-10-17; it is the VTX's input draw, not its RF output.
