T-Motor F55A Pro III 55A 3-8S TPHR8504 MOSFET 4-in-1 ESC

The T-Motor F55A Pro III is a 4-in-1 ESC for 3-8S FPV builds, using TPHR8504 MOSFETs and an STM32G071 controller for stable high-current output.

Key features

• A wide 16-128kHz PWM range auto-adjusts to the motor's KV for smoother throttle response.

• A dual oxide heat-sink design and added TVS protection improve heat dissipation and durability under hard flying.

• It mounts plug-and-play with T-Motor's F7 Pro flight controller.

• Supports DShot150/300/600/1200 with telemetry for real-time current and temperature monitoring.
