Happymodel CrazyF405HD AIO (ELRS)

Overview:
The CrazyF405HD ELRS combines an STM32F405 flight controller, 12 A 4‑in‑1 BLHeli_S ESC, ExpressLRS V3 serial receiver, barometer, and black-box storage into a compact 25.5mm board. Designed for 1-2 S builds like whoops, cinewhoops and toothpicks, it supports Betaflight and INAV firmware and removes older components to streamline layout and reduce weight. This ready-to-fly AIO solution offers HD-ready control with full telemetry, high-speed ESC performance and integrated voltage/current sensing - all in under 5g. This compact, feature-packed flight controller suits drone builders seeking high-end performance in micro HD builds. Its integrated ELRS link, efficient ESC hardware, and telemetry features make it a standout for HD whoop or toothpick projects.
