Hobbywing XRotor Micro 30A ESC 30901077 - Compact FPV Speed Controller  [HW-30901077]

Compact ESC Built for FPV Pilots

The Hobbywing XRotor Micro 30A ESC, model number 30901077, is a compact, high-performance electronic speed controller aimed at FPV pilots. It runs the original BLHeli_32 firmware to deliver consistent functionality and flexible tuning options for experienced flyers.

High-Grade Electronics and PCB Design

This unit uses a 32-bit ARM processor at 48MHz together with premium Fairchild MOSFETs and ceramic capacitors. The 3-in-1 drive ICs and a four-layer PCB with 3-ounce copper trace work together to improve durability and thermal performance for demanding FPV use.

Quiet, Accurate Throttle Response

Hardware-generated PWM provides smooth throttle transitions and reduced noise. The damped light mode adds regenerative braking and active freewheeling for quick motor slowdown, which helps with precise flight handling in tight manoeuvres.

Programmable Options and Protections

With the original BLHeli_32 firmware, the ESC supports simultaneous programming of multiple units through Cleanflight or Betaflight tools. Built-in protections include motor lock detection, temperature safeguards, low RPM power limits, low-voltage cutoff, and current protection to extend component life.

This Hobbywing XRotor Micro 30A ESC is aimed at FPV enthusiasts who want compact, programmable control with reliable protection features for racing and freestyle builds.
