It can handle 3–6S voltage and up to 45A per channel. At its core is a 32-bit MCU running at up to 120 MHz with AM32 firmware installed, delivering the latest in ESC technology.\u003c\/p\u003e\n\u003cp\u003eThe XRotor Micro offers smooth and responsive control thanks to its dynamically adjustable PWM frequency (48–96 kHz). It supports a wide range of input protocols, including standard PWM, Oneshot125, Oneshot42, Multishot and DShot (up to DShot1200), with automatic detection on startup.\u003c\/p\u003e\n\u003cp\u003eFor added functionality, the ESC features a built-in voltage and current sensor to provide real-time telemetry to your flight controller. It also comes with an onboard 5V BEC, capable of powering your FC, receiver and other accessories. Soft mounting grommets are included to help reduce vibration transfer and ensure reliable operation in demanding builds.\u003c\/p\u003e\n\u003cp\u003eCompact, powerful and reliable, the XRotor Micro 45A is a top choice for racers and freestyle pilots who need maximum performance in a 20×20 stack.\u003c\/p\u003e\n\u003ch3\u003eFeatures\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eHigh-performance 32-bit ARM MCU running at up to 120 MHz with AM32 firmware\u003c\/li\u003e\n\u003cli\u003eDynamic PWM frequency (48–96 kHz) for smoother and more efficient motor control\u003c\/li\u003e\n\u003cli\u003eSupports standard PWM (1–2 ms), Oneshot125, Oneshot42, Multishot and DShot (up to DShot1200) with automatic signal detection\u003c\/li\u003e\n\u003cli\u003eAdvanced braking (damped light) for fast motor retardation and active freewheeling\u003c\/li\u003e\n\u003cli\u003eBuilt-in voltage and current sensor for telemetry feedback to the flight controller\u003c\/li\u003e\n\u003cli\u003eIntegrated 5V BEC for powering FC, receiver and accessories\u003c\/li\u003e\n\u003cli\u003eBuilt-in beacon function — ESC can beep after inactivity, helping locate a lost model\u003c\/li\u003e\n\u003cli\u003eSoft mounting grommets included to reduce vibration transfer to the flight controller\u003c\/li\u003e\n\u003cli\u003eCompact 20×20 mm form factor with up to 45A continuous current per channel (3–6S LiPo)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eModel: XRotor 45A 4-in-1 (20×20 mm) AM32\u003c\/li\u003e\n\u003cli\u003eApplication: FPV drones with 130–280 mm wheelbase\u003c\/li\u003e\n\u003cli\u003eInput Voltage: 3–6S LiPo\u003c\/li\u003e\n\u003cli\u003eContinuous Current: 45A × 4\u003c\/li\u003e\n\u003cli\u003eBurst Current: 55–60A × 4 (10s)\u003c\/li\u003e\n\u003cli\u003eBEC Output: 5V \/ 1.5A\u003c\/li\u003e\n\u003cli\u003eMCU: 32-bit ARM (up to 120 MHz) running AM32 firmware\u003c\/li\u003e\n\u003cli\u003ePWM Frequency: 48–96 kHz (dynamic)\u003c\/li\u003e\n\u003cli\u003eSignal Protocols: PWM, Oneshot125, Oneshot42, Multishot, DShot (up to DShot1200, auto-detect)\u003c\/li\u003e\n\u003cli\u003eThrottle Calibration: Supported\u003c\/li\u003e\n\u003cli\u003eESC Programming: Stick programming or via FC\u003c\/li\u003e\n\u003cli\u003eFunctions: DEO (damped light), adjustable timing, motor rotation, beacon mode\u003c\/li\u003e\n\u003cli\u003eInput Wires: 14AWG, 100 mm (red\/black)\u003c\/li\u003e\n\u003cli\u003eOutput Wires: Solder tabs (no wires fitted)\u003c\/li\u003e\n\u003cli\u003eConnector: XT60 plug included (not factory-installed)\u003c\/li\u003e\n\u003cli\u003eDimensions: 40 × 33 × 5 mm\u003c\/li\u003e\n\u003cli\u003eWeight: 12 g (with wires)\u003c\/li\u003e\n\u003cli\u003eMounting: 20 × 20 mm (M3)\u003c\/li\u003e\n\u003cli\u003eLow ESR capacitor (pre-soldered to power leads)\u003c\/li\u003e\n\u003cli\u003eJST signal cable set\u003c\/li\u003e\n\u003cli\u003eXT60 connector (loose)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eIn the box\u003c\/h3\u003e\n\u003cul\u003e\u003cli\u003e1× XRotor Micro 45A AM32 4-in-1 ESC\u003c\/li\u003e\u003c\/ul\u003e","brand":"Hobbywing","offers":[{"title":"Default Title","offer_id":58941056549196,"sku":"ESC-HWXR45A","price":57.9,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1087\/9952\/5196\/files\/HW-XRotor-Micro-40A.jpg?v=1790285961","url":"https:\/\/dronepart.co.uk\/products\/hobbywing-xrotor-micro-20-20-45a-4-in-1-3-6s-am32-esc","provider":"My Store","version":"1.0","type":"link"}
