Hobbywing 31001001 XRotor Nano F4 Flight Controller Compact Racing FC  [HW-31001001]

Small Form Factor, Big Flight Performance

The Hobbywing XRotor Nano F4 Flight Controller, model number 31001001, packs full-featured flight control into a 27x27mm board that suits 130mm mini quads and similarly compact frames while retaining advanced flight capabilities.

Protocol and Pulse Mode Support

This board handles a wide range of signal modes including PWM, Oneshot125, Oneshot42, Multishot and the DShot family up to DShot1200, giving reliable digital and analog throttle timing for FPV racers and freestyle pilots.

Fast MCU for Tight Flight Loops

Powered by the STM32F405 MCU, the XRotor Nano F4 provides the processing headroom to run higher PID loop rates and increased gyro sampling, improving stability and responsiveness in aggressive flight.

Integrated Power and On Screen Data

The built-in BEC supplies 5V at 1.5A to on-board gear and the internal OSD exposes telemetry and setup options through Betaflight or Cleanflight, simplifying in-field tuning and race prep.

Neat Wiring with Hobbywing ESCs

While compatible with many ESC brands, the controller was designed to pair cleanly with the Hobbywing XRotor Nano 4in1 ESC to reduce cabling and make installation more straightforward.

A practical choice for builders who want a compact, high-performance flight controller that supports modern protocols and integrates easily with Hobbywing hardware.
