HDZero Gamma 45A HD-Ready AIO

Product detailed description

HDZero Gamma 45A HD-Ready AIO is a compact all-in-one flight controller + 4-in-1 ESC built for digital FPV setups where you want clean wiring, low weight, and reliable power delivery for a digital VTX. It combines a powerful STM32G473 flight controller, an integrated ExpressLRS receiver, and a 32-bit 4-in-1 ESC on a single board — ideal for lightweight 2.5–4 inch FPV builds running 3–6S.
