BS-55A 2-6s 4 In 1 55A / 40A ESC BLHeli_S Speed controller board Support Dshot150 Dshot300 Dshot600 for RC Drone FPV Racing Models

Description

It is no longer necessary to calibrate the ESC throttle stroke. The precise ESC signal is the biggest advantage of digital signal. PWM is an analog signal, which is prone to waveform distortion during transmission. Compared with the current value of 1000~2000, the trip of Dshot is 0~2048. Speed above, faster than oneshot ESC protocol. Security, Dshot comes with four-bit cyclic redundancy check (CRC).
