RUSHFPV XSPAN 3.1-3.8GHz 5W

Where this data comes from

Board marking 31385. Label: power steps PIT / 25 / 200 mW / 1 W / 5 W, four bands printed as MHz spans (3330-3470, 3170-3310, 3490-3630, 3650-3790), eight channels per band, 7-30 V Lipo-in. The 3.17-3.79 GHz range is those four spans end to end; the model is sold as '3.1G-3.8G'. X-SPAN is RushFPV's name for its wideband analog module line - a standalone brick with an SMA jack, a fan and a dual DC-in that also feeds the camera, not a board you bolt into a stack. RushFPV publishes no weight and no mounting pattern for the class, so those columns stay empty. Output above the lowest step is licensed spectrum in most countries; the module's own label carries that reminder.
