Product description
The FT ESC 75A 4-in-1 speed controller combines 4 channels with a continuous current of up to 75A each and is designed for a 3–6S battery power supply. This configuration allows the use of a single board to control four motors, simplifying the layout of the power section.
The 75A ESC operates on an 8-bit EFM8BB21 MCU with Bluejay firmware. It supports control via PWM, DShot 300, and DShot 600 protocols. The controller features a built-in analog current sensor to monitor the power system load; however, telemetry transmission is not supported in this model.
The board is built on a 6-layer PCB with 3oz copper. Mounting holes of 30.5 × 30.5 mm for M3 hardware simplify installation into the frame. Dimensions are 74 × 85 mm.
