FlyingRC 4-in-1 75A ESC is a 4-in-1 controller suitable for 4-12" drones powered by 3-7S LiPo batteries. This board is aimed at heavier freestyle and long-range builds where a high current reserve is needed.
The controller can handle 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 casing is in direct contact with the chip, allowing heat to be dissipated well. 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 included 680uF/35V capacitor and the power cable with XT60 connector must be soldered to the controller.
The controller has a mounting pattern of 30,5x30,5mm with M4 mounting holes (M3 with softmount). It connects to the FC via an 8-pin SH1.0 cable.
