Product description
The FT ESC 85A 4-in-1 speed controller combines 4 channels with a continuous current of up to 85A and is designed for a 6–12S power supply. The 85A ESC is perfectly suited for heavy-lift quadcopters (13–21 inches) with 42xx, 52xx, and 62xx motors.
The model is powered by a 32-bit ARM microcontroller running at 120 MHz and features AM32 v2.18 firmware. The device supports PWM, Oneshot, Multishot, and digital DShot protocols. The board dimensions are 113 × 76 mm.
The speed controller is equipped with a 5V / 5A BEC to power compatible peripherals. External capacitors and TVS diodes are responsible for filtering and protection. Mounting holes of 30.5 × 30.5 mm simplify installation into a compatible stack.
