HAKRC F7226 40A AIO Flight Controller with BLHeli_S ESC – 2–6S, STM32F722, OSD, Barometer, 5V/3A BEC, CRSF & DSMX Receiver Support

The HAKRC F7226 AIO Flight Controller is a high-performance all-in-one FC+ESC solution for FPV racing drones and freestyle builds. Featuring an integrated 40A 4-in-1 ESC with BLHeli_S firmware, this compact 32×32mm stack supports 2S–6S LiPo input and delivers smooth, efficient performance with full protocol support including DShot600.

Built with a premium 8-layer PCB, 2oz copper thickness, and imported 40V high-current MOSFETs, this AIO board offers superior durability and heat dissipation under high load. The onboard STM32F722RET6 CPU, ICM42688 IMU, AT7456E OSD, and barometer provide high-precision flight data processing, while the 5V/3A BEC powers your peripherals.
