SimonK firmware designed explicitly for ESCs (electronic speed controllers) that offer a faster response compared to normal ESC firmware. This is a highly recommended ESC for use in multi-rotor aircraft like quadcopter, hex copter, and octocopter. SimonK ESC 30A (ELECTRONIC SPEED CONTROLLER) is capable of driving motors which consume up to 30A current. It works on 2S-3S LiPo batteries. An onboard BEC present in which provides regulated 5V(2A max draw) to power the flight controller and other onboard modules which consume current up to 30A. It used to control our Brushless motors can be with a 2S-3S LiPo battery under the condition that the motor doesn’t draw more than 30A of current. Simonk ESC 30A recommended to use with A2212 brushless motor (1000kv, 1400kv, 2200kv).
SimonK ESC 30A features backward-polarity protection and protection on the 5V receiver line. In short, it means that if you connect a battery backward won’t destroy your motor controller and other BECs won’t affect the ESC.
In an electric-powered radio controlled model, Battery Eliminator Circuit is typically part of the electronic speed control(ESC). BEC allows to carry only one battery ie, the motive power battery, instead of two,(motive power, and a separate battery to operate the R/C equipment. Battery Elimination Circuit is somewhat similar to the voltage regulator. It converts the main LiPo battery pack voltage to a lower voltage (e.g. 2S 7.4V, 3S 11.1V, or 4S 14.8V to 5V). SimonK ESC 30A features a throttle calibration function. This helps you to adapt to different remote throttle travel differences and improve throttle response smoothly. As it provides low voltage protection, the motor will not start immediately, regardless of the throttle stick in any position.
