NZFPV Hakrc F4126 20A AIO F411 CPU 2S-5S BLHeli_S

Integrated and Robust Design

The HAKRC F4126 AIO combines a flight controller and a 4-in-1 ESC on a single 32x32mm board, simplifying wiring and saving space in compact FPV drone builds. Its high-end 8-layer PCB with 2oz thickened copper skin enhances overcurrent capability and provides excellent heat dissipation. This robust construction ensures durability and reliable performance, making it ideal for demanding micro drone applications.

Quality Components for Flight Stability

At its core, the F4126 AIO features the STM32F411CEU6 CPU and ICM42688 IMU, delivering responsive flight control with the HAKRCF411D firmware. The ESC section incorporates imported 30V high-current-resistant MOSFETs for longevity, an industrial-grade LDO for high-temperature resistance, and high-quality Japanese Murata capacitors for superior filtering performance. These components ensure stable and dependable operation across various flight conditions.

Feature-Packed for Modern FPV

The F4126 AIO is equipped with an AT7456E chip for On-Screen Display (OSD), an integrated barometer for altitude sensing, and a 16MB black box for flight data logging. It includes a 5V/3A BEC to power peripherals, a built-in current sensor, and support for adjustable LEDs. The integrated 20A ESC (25A peak) runs BLHELI_S (G-H-30) firmware, supporting PWM, Oneshot125, Oneshot42, Multishot, Dshot150, Dshot300, and Dshot600 protocols on 2S-5S LiPo input.
