Features: Developed for Multicopter Very compact Precision speed control (about 950 steps) very fast FET switching through the use of special gate drivers Minimal dead time, setted adaptive 2-4S LiPo capable LED onboard adaptive Auto Timing 32Khz PWM Frequenz 50-500Hz input signal(PWM) or oneshot125 (up to 2000Hz) no external Cap (electrolytic capacitor) is necessary ** fast reacting gas change linear throttle response Active wheeling enabled (little diode losses resulting in higher efficiency) Regenerative braking, therefore quick throttle response when decelerate (the ESC uses active wheeling and regenerative braking, 2 independent features which relates to each other in different working states) Hardware and Software are developed for each other, all Parameters are optimized, we are sure you wont find another similar sized ESC which stays as cool and react as fast as this ESC at the same Ampere draw. Due to this special integration of hard and software some features are realized which allow the ESC to peform at a real high end level, no one reacts or brakes faster on a 14 Pole Motor (quite common) RPM up to 42.000 are supported, which is simply amazing. Given this high Pole count Motors arent a problem too for this ESC too. Oneshot125 is an alternative PWM throttle Signal that is 8 times shorter/faster then the Standard 400-490Hz signals are. It is meant to be sent instantly after each FC controll loop to have the fastest possible ESC Response. Oneshot Signal transmission is deeply integrated in the ESC and is a flawless experience by just setting one solder jumper (just optional, normal PWM works of course too). The Kiss ESC is easy to use, you wont need to do long test runs to find good settings, the Kiss ESC simply work. Specifications: Size: 22 x 12 x 4mm/0.9 x 0.5 x 0.2 inch Package size: approx. 56 x 79mm/2.2 x 3.1inch Net weight: 2g Package included: 1 x panel Notes: Do not directly mount the ESC on conductive material such as carbon fiber or aluminum . Depending on the configuration, they also need GND connected instead of only the signal for FC because especially at 3.3V CPUs ( ARM Cortex for example ) a clean GND reference can be useful.
