Description

A BLHeli Sย 20A ESC designedย for use with Holybro’s 2216-880KV Motorย / X500 Quadcopter Kitย (V1 and V2). The ESC is slim so can fit within 16MM booms.

It comes with long wires andย pre-solderedย connectorsย for a quick and easy installation – please select connector option as required.

Main features

โ—ย EFM8BB21F16G MCU, pipelined 8-bit C8051 core with 50 MHz maximum operating frequency.
โ— Dedicated high frequency driver, makes the start more smooth. ESC maximum speed is 500k eRPM.
โ— BLHeli-S firmware is designed for superior performance in multirotors, and uses hardware generated motorย pwm for smooth throttle response and silent operation.
โ— Damped light does regenerative braking, causing very fast motor retardation, and inherently also does activeย freewheeling.
โ— Supports higher KV motor and more power load.
โ— The code supports regular 1-2ms pulse width PWM input, as well as Oneshot and Multshot . The input signal isย automatically detected by the ESC upon power up.
โ— Supports Dshot150, Dshot300 and Dshot600. Dshot is digital signal, anti-interference ability is strongerย andย do not need throttle calibration.
โ— The silicone twisted-pair of the throttle signal cable reduces the crosstalk caused by signal transmissionย and makes flight more stable.

    Hi, sorry Holybro don't provide that information. Usually it's around 1000us to 2000us.

Advice

Here at Flying Tech we have a wide choice of electronic speed controllers (ESCs).

There are two main types of ESCs: 4-in-1 ESCs and single ESCs. A 4-in-1 ESC integrates four individual ESCs onto a single circuit board, each controlling a separate motor. A single ESC controls only one motor.ย 

This 4-in-1 ESC is a more popular choice for racing quads, while single motor aircraft such as fixed wings would use a single ESC. Single ESCs are still used by some drone racers though, as after a crash or a burnt up ESC, they only have to replace one, not an entire 4-in-1 or stack which is a lot more costly. Single ESCs are also available which much greater current ratings (80amp +) so they are also used by power hungry multi-rotors, for example X-Class racing quads, professional camera flying โ€œCineliftersโ€.ย 

When using individual ESCs, they typically need to be connected to a single power distribution board (PDB) or an โ€œAIO flight controllerโ€ (a type of flight controller with integrated PDB) for power supply.
