Extremely compact design of the XRotor Nano 20A 4in1 controller with its 4 high performance 20A controllers and simple wiring with the Hobbywing XRotor Nano Flight Controller. The controller was developed especially for smallest FPV Racecopter.
Powerful EMF8BB21F16G MCUs with an operating frequency of up to 48MHz, high quality components such as the latest MOSFETs and ceramic capacitors ensure high efficiency and fast reactions in flight.
The 4in1 Nano controller uses the original BLHeli-S firmware A-H-50 16.5 which offers the possibility of various adjustment possibilities and firmware upgrades. The 4in1 Nano controller supports Oneshot125/Oneshot42/Multishot and DShot150/300/600 modes which offer the fastest controller response.
Hardware supported Generated PWM and Damped Light Mode result in quiet motor running and with regenerative braking operation you achieve a very fast and effective deceleration of the motors.
