Holybro Atlatl HV 5.8G 3W Pro VTx

Where this data comes from

Read 2026-09-25 off Holybro's own shop, the sixteenth VTX manufacturer catalogue read beside the US retail scrape and the fourth brand this catalogue carried no transmitter of at all (it already carries Holybro stacks, one of which ships this very module). holybro.com is Shopify: products.json?limit=250 is the whole catalogue in one request (178 SKUs, page=2 empty), product_type is the brand's own class label and 'VTX & OSD' holds five parts - these four transmitters and a Micro OSD V2. The labelled spec block is in body_html; nothing sits in the page HTML that is not in it, and docs.holybro.com (323 pages, all autopilot) documents no Atlatl. This is SKU 13040, the Pro version of /products/atlatl-3w-vtx; the Standard (SKU 13038) is a separate entry. Holybro sells them as one product with a 'Version' option, but every differing figure is printed in its own labelled half of the same block - power 'Pro version:25mW, 400mW, 600mW, 1.6W & 3W' against the Standard's five steps, dimensions 'Pro: 53.79 mm x 27.8 mm x 13.5 mm' against 'Standard: 40.8 x 24.8 x 13.3mm', operating mode 'Smart Audio (Standard), IRC Tramp (Pro)' - and each version has its own SKU, its own fifteen-image and eight-image photo sets, and its own Betaflight VTX-table file. The Pro's (BTFL_vtxtable_W1.json) carries real values, 25/400/600/1600/3000, and its seven bands and 56 channels agree with the page's frequency table, whose edges are 4990 and 5945 MHz. input_voltage is this board's own case print, '9-28V DC-IN / GND / DATA / VIDEO / GND / 5V-OUT', read at full resolution - the Standard's case says 7-36V, which is how two boards on one page were told apart; the block's '2~6s' is a cell count and not a voltage. mount_mm is EMPTY: the brand publishes a dimension drawing for the Standard only, and nothing states this larger fan-cooled body's hole pattern. weight_g is EMPTY too - the one figure is a scale photograph reading 30.9 g with the supplied pigtail attached.
