FlyingRC 4in1 75A ESC is a 4in1 controller suitable for 4-12" drones powered by 3-7S LiPo batteries. This board is aimed at heavier freestyle and long-range builds where high current reserve is needed.
The controller handles a continuous current of 75A per channel. The ESC is equipped with gold-plated Infineon IRF7480 MOSFETs with an on-state resistance of only 0.95mΩ, whose metal package is in direct contact with the chip, ensuring efficient heat dissipation. The PCB has 10 layers with 2oz copper and four surface-soldered gold-plated copper strips that help conduct current and reduce resistance and heat generation. Control is handled by a 32-bit QF32F4AK8U7 processor at 120MHz with an integrated ID6288 driver. The controller uses AM32 firmware, supports DShot150/300/600, OneShot and PWM, and handles sinusoidal startup with high torque at low RPM. It includes a current sensor with scale 100. The supplied 680uF/35V capacitor and power cable with XT60 connector must be soldered to the controller.
The controller has a mounting spacing of 30,5x30,5mm with a mounting hole M4 (M3 with softmount). It connects to the FC with an 8-pin SH1.0 cable.
FlyingRC is a drone and robotics electronics brand whose development team is based in Singapore.
