The Atto is a sub-gram 2.4 GHz Ghost receiver built for pilots who care about every milligram and every square millimetre. At 0.6 g and 14.8 × 11.5 mm, it's one of the smallest FPV receivers on the market — 15% smaller than its closest competitor — and it doesn't compromise on range, protocols, or reliability.
