Holybro Atlatl HV 5.8G 3W 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 13038, the Standard version of a page that sells two boards under one URL; the Pro (SKU 13040) is a separate entry. The shared block prints Frequency 5.8G, '7 bands: A, B, E, F, R, L, X', 'Transmission Channel: 56', Operating mode 'Key button, Smart Audio (Standard), IRC Tramp (Pro)', Transmission power 'Standard: 25mW,1.6W, 2W, 2.5W, 3W' against 'Pro version:25mW, 400mW, 600mW, 1.6W & 3W', Antenna connector MMCX, Voltage input 2~6s, Current consumption 1.3A/12VDC @ 3000mW, RF impedance 50 ohm, input video 75 ohm CVBS 0.8~1.2Vp-p NTSC/PAL, and Dimensions 'Standard: 40.8 mm x 24.8 mm x 13.3mm' against 'Pro: 53.79 mm x 27.8 mm x 13.5 mm'. The page's own indicator-light legend counts this version's five steps again (25mW/1.6W/2W/2.5W/3W), which is why the top step publishes: unlike SpeedyBee's TX ULTRA and Axisflying's ROCK, the brand numbers it. frequency_range is the page's own 7x8 frequency table, whose edges are 4990 MHz (X1) and 5945 MHz (E8) - the same span the Skyzone/ATOMRC 7-band boards carry. mount_mm and input_voltage are the brand's own, but not from the block: the dimension drawing in its images annotates 41 mm x 25 mm x 13.5 mm around a 20 mm x 20 mm hole pattern, and the case is silkscreened '7-36V DC-IN / GND / DATA / VIDEO / GND / 5V-OUT'. The block's '2~6s' is a cell count and not a voltage, so it stays here rather than in the field. weight_g is deliberately EMPTY: the only figure the brand publishes for this board is a scale photograph reading 22.6 g, and the thing on the scale is the module with the supplied 80mm SMA-MMCX pigtail attached - the kit-weight rule. (The Shopify variant's own 'weight':50 is a shipping weight, identical for both versions.) One hazard recorded: the brand's Betaflight VTX-table JSON for this version (atlatl_3W_vtx_table.json) is corrupt where its own page is not - its E band reads 5705,5685,5665,5665,5885,5905,5905,5905 where the page's table prints 5705,5685,5665,5645,5885,5905,5925,5945 - and its power labels are Betaflight's three-character display strings ('25 ','1.6','2.0','2.5','MAX'). Bands and channel count from it; numbers from the page. Both versions read as unavailable on 2026-09-25.
