Product overview
The HAKRC 40AminiF7 Stack combines an F722 flight controller with a BLHeli-32 four-in-one ESC for UAV flight control and motor control integration. Its physical architecture uses two compact boards: the controller measures 31*30*8mm and weighs 6g, while the ESC measures 31*30*6 mm and weighs 6.1g. Both use 20*20mm mounting positions, with φ4mm controller holes and an M3 ESC aperture specification. This is an electronics stack for installation within an aircraft, rather than a complete flight platform or an airframe-only kit.
The controller combines an STM32F722RET6 processor, MPU6500 IMU, Infineon DPS310 barometer, AT7456E OSD and 16MB blackbox storage. Five UARTs, receiver interfaces, Type-C USB and a built-in DJI FPV Air System connector provide integration options. Power specifications differ between boards: the controller accepts 3—6S input and provides 5V/3A and 9V/2.5A BEC outputs, while the ESC lists 2-6S operation, 40A maximum continuous current and 45A maximum instantaneous current. Configuration software is betaflight-configurator for the controller and BLHeli 32 for the ESC.
