HOBBYWING XRotor Micro 40A 4in1 ESC 30901076 - Compact FPV Controller  [HW-30901076]

Miniature 4-in-1 ESC for competitive FPV

The Hobbywing XRotor Micro 40A 4in1 ESC offers four 40A channels in a narrow footprint for pilots building race or freestyle quads. Onboard BEC and an amp/volt telemetry port make it easy to integrate into compact frames where space is limited.

Robust hardware for tight control

Driven by EMF8BB21F16G MCUs at up to 48MHz and fitted with quality MOSFETs and ceramic capacitors, this ESC is engineered for lower thermal loss and efficient operation. The six-layer PCB with heavy copper traces improves current handling and response.

BLHeli-S and DShot digital support

Delivered with BLHeli-S firmware, the XRotor Micro allows flashing via the throttle signal or a supported flight controller. DShot150/300/600 support reduces signal distortion and speeds up ESC reaction for accurate stick-to-motor feel.

Quiet running and precise braking

Hardware-generated PWM produces smooth throttle curves and quieter motors. With damped light enabled, the ESC offers regenerative-like braking and quick motor slowdown for improved handling during abrupt throttle changes.

Suited to 130-280mm FPV machines, the Hobbywing XRotor Micro 40A 4in1 ESC balances small size with programmable features for competitive flying.
