Hakrc F4126 40A AIO F411 CPU 2S-6S BLHeli_S

Robust 40A BLHeli_S ESC

The HAKRC F4126 40A AIO features an integrated 4-in-1 ESC delivering 40A continuous current and 45A peak, ideal for powerful FPV drone setups on 2S-6S LiPo batteries. Running BLHELI_S (G-H-30) firmware, it supports PWM, Oneshot125, Oneshot42, Multishot, Dshot150, Dshot300, and Dshot600 protocols for smooth, responsive motor control. Imported 40V high-current-resistant MOSFETs ensure longevity and strong load capability, enhancing reliability under demanding conditions.

Advanced Flight Control and Sensors

The flight controller is powered by the STM32F411CEU6 CPU and ICM42688 Inertial Measurement Unit (IMU), providing precise flight data processing with HAKRCF411D firmware. It includes an AT7456E chip for On-Screen Display (OSD), an integrated barometer for altitude hold, and a 16MB black box for flight log recording. A built-in current sensor and 5V/1.5A BEC support essential peripherals, while programmable LED support adds visual customization.

High-Quality Construction and Components

The F4126 40A AIO is built on a high-end 8-layer PCB with 2oz thickened copper and a resin-plugged hole production process, featuring a double pad design for superior overcurrent capacity and heat dissipation. It incorporates an industrial-grade LDO for high-temperature resistance and high-quality Japanese Murata capacitors for exceptional filtering performance, ensuring system stability and longevity in challenging FPV environments.
