The Cicada line is the BLHeli_S series from Sunrise. The design uses hardware PWM for ultra smooth motor response. Oneshot 125, Oneshot42 and Multishot are auto-detected. Dshot 150, 300 and 600 are supported without making any modifications (input caps have been removed). B2 processor operating at 48MHz
Four 20A ESCs are packed onto a board with the common 30.5x30.5mm mounting holes so you combine it into a space saving stack with a flight controller. It is well matched for a build using 1407 - 2205 motors, 4-6" props and 3S-4S power.
Like most multirotor ESCs, there is no 5V supply provided to the flight control board or other devices.
20A constant, 25A burst
