The Hobbywing XRotor Micro 45A 4-in-1 ESC and Flight Controller Combo is highly integrated with the latest features and hardware designs, as well as incredibly compact. Featuring upgraded 45A x4 ESC, 3rd-generation BLHeli-32 firmware support and a voltmeter module that allows the flight controller to monitor battery voltage and amperage in real time. Included with this combo is an updated F7 Flight Controller featuring OSD, and voltage monitoring. This powerful combo is a high performance and convenient way to complete your next FPV build.

Features:
Specially tailored for competition level FPV!
Highly Integrated and compact
20x20mm ultra-small mounting hole spacing design to reduce size and weight
High performance 32-bit microprocessor with a running frequency of up to 120MHz for excellent performance
Third generation BLHeli_32 code can support up to 128KHz PWM output frequency, which can be compatible with more motors
Damped light that regenerative braking, causing very fast motor retardation and active freewheeling
Can be dynamically adjusted for precision throttle control
Tunable parameters that can make the code run well even in the most demanding situations
Dshot signaling is supported at any rate up to Dshot1200
The input signal is automatically detected by the ESC upon power up
Supports beacon functionality, where the ESC will start beeping after a given time of zero activities, which can be very useful for finding lost crafts
Thermal Protection that measures temperature within the MCU and limits motor power if the temperature is too high
Supports stall protection, where If the motor has attempted to start but not succeeded for a few seconds, it will stop attempting and wait for throttle to be zeroed before attempting again
Supports motor timing between approximately 10 and 310 degrees
