This is BLHeli-S20A-D-A.
In the market there mainly 3 type of ESC are available 1) Oneshort ESC, 2) Opto ESC, 3) D-Short ESC. So this is D-Short ESC this best drone flight controller for your drone project it gives power to BLDC motor to gain quality of speed, It use BLHeli technology. D-Shot is a protocol that flight controllers use for communicating with ESCs. It stands for ‘Digital Shot’. It is a new digital communication protocol developed by Flyduino in collaboration with Beta flight as an alternative to Oneshot and Multishot. Oneshot and Multishot (and standard PWM) all use analogue signals This is the fastest ESC protocol among all the above with a maximum frequency of 32 kHz. It is 10 times faster than Oneshot125
Electronic speed controllers (ESCs) are devices that allow drone flight controllers to control and adjust the speed of the aircraft’s electric motors. A signal from the flight controller causes the ESC to raise or lower the voltage to the motor as required, thus changing the speed of the propeller, It’s helps prevent a vehicle from skidding – and the driver from losing control of his or her vehicle – when turning a corner, braking sharply or making a sudden maneuver. ESC technology automatically activates the brakes to help steer the vehicle in the right direction
