The 4-in-1 ESC not only includes 4 high-performance 40A ESCs, 1 built-in BEC, but also an Amp/Volt monitoring port which allows FC to monitor the volt & amp in real time (on condition that the FC supports this function); it’s as small as a FC for FPV(s) and easy for installation and wiring. With the remarkably small size, it's a perfect match for competition FPV(s).
The use of EMF8BB21F16G MCUs with the operating frequency of up to 48MHz, imported high quality MOSFETs, 3-in-1 drive ICs and ceramic capacitors, 3-ounce copper, and 6 layers of PCBs guarantees less heat, higher efficiency and rapider response.
The ESC (with great performance and rich functions) uses the original BLHeli-S firmware and supports adjusting parameters or upgrading firmware via different methods (i.e. via throttle signal wire with using other development board or a FC flashed with the cleanfight/betaflight firmware).
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.
