Product overview
The HAKRC HKF4126 AIO combines flight-controller and ESC functions in a 31*31mm board weighing 7g. Its listed item name is HAKRC F411 35A AIO. Integration requires accommodation for either 25.5*25.5mm or 26.5*26.5mm mounting hole spacing. The controller uses an STM32F411CEU6 CPU, ICM42688 IMU, AT7456E OSD and BMP280 barometer, with a current meter and HAKRC F411D firmware. Programmable LED support includes WS2812, while the receiver list covers Frsky, Futabas, Flysky, TBS Crossfire and DSMX:DSM2.
The ESC uses BLHELI_ S (G- H-30) firmware and accepts PWM, Oneshot125, Oneshot42, Multishot and Dshot150/300/600 signals. Its specified input is 2S-6S LiPo, with 35A continuous current and 40A peak current. Physical construction includes an eight-layer PCB with 2oZ copper, 30V MOS components, an industrial-grade LDO and Japanese Murata capacitors. These address current handling, heat dissipation and filtering. The supplied configuration is one HAKRC 35A AIO flight controller, making this a board-level component purchase.
