XRotor Nano Compact ESC - Hobbywing 30901068 - XRotor Nano 20A 4in1 ESC for FPV Drones  [HW-30901068]

High Density 4in1 ESC for Tiny Quads

The Hobbywing XRotor Nano 20A 4in1 ESC integrates four 20A ESC channels into one compact board, ideal for tight frame builds and small racing quads. Its reduced wiring footprint simplifies assembly and helps keep centre-of-gravity low.

Performance-Focused Circuit Design

With an EMF8BB21F16G MCU up to 48MHz, imported MOSFETs, combined 3-in-1 drive ICs, ceramic capacitors and a six-layer PCB, the unit aims to cut thermal buildup and maintain snappy ESC responses for precise flying.

BLHeli-S Firmware with Broad Protocol Support

Preinstalled with BLHeli-S, the ESC supports parameter adjustments and firmware flashing via a throttle signal or through a flight controller using Cleanflight or Betaflight. It handles PWM, Oneshot125, Oneshot42, Multishot and DShot150/300/600 for fast, reliable control.

Stable Throttle and Braking Modes

Hardware PWM delivers smooth throttle transitions and reduced motor noise. The damped light option provides regenerative braking for better control when slowing down or performing tight lines.

The Hobbywing XRotor Nano 20A 4in1 ESC is a solid choice for builders seeking modern ESC features in a tight package for small FPV quads.
