The XRotor Nano 20A 4in1 BLHeli-S DShot600 not only includes 4 high-performance 20A ESCs, but also a volt monitoring port which allows FC to monitor the voltage in real time (on condition that the FC supports this function). With the incredibly small size, the installation and wiring can be very simple and easy when pairing it with the Hobbywing XRotor Nano Flight Controller. Both can be stacked together very easily with their 20x20mm mounting pattern. This ESC is specially designed for super mini-sized indoor FPV(s).
Besides the regular PWM mode, Oneshot125/Oneshot42/Multishot modes, the latest DShot150/300/600 modes are also supported. In DShot150/300/600 modes, the ESC has great anti-interference performance and rapid response.
The ESC firmware uses hardware generated motor pwm for smooth throttle response and silent operation. Damped light does regenerative breaking, causing very fast motor retardation, and it inherently also does active freewheeling.
