Product overview
The HOBBYWING XRotor Micro 45A 4in1 BLHeli32 6S combines four motor controllers on a 46 x 40 x 6.3mm board weighing 11.5g. Intended for competition FPVs, its listed application range is 130–300mm. The architecture incorporates two BEC outputs, rated at 5V/1.5A and 10V/1.5A, plus battery voltage and current measurement for a connected flight controller. Its electronics use 32-bit ARM MCUs running at up to 48MHz, with 3-in-1 drive ICs, MOSFETs, ceramic capacitors and six-layer PCB construction using 3-ounce copper.
The input configuration comprises 130mm red and black 12AWG leads and an XT60 connector with wires soldered on. Motor outputs use solder tabs, with no output wires or connectors supplied. Installation combines a soft-cable connection with shock-absorbing mounting holes; the stated preferred pairing is the XRotor Micro-F4-G2 flight controller. Electrical integration must accommodate a 3–6S LiPo input and ratings of 45A continuous and 60A peak per channel. BLHeliSuite32 programming, multiple analog and digital throttle modes through DShot1200, hardware-generated motor PWM and Damped Light braking provide configurable motor control.
