Brand: 
DYS multicopter parts
Collection: 
SKU:
ESC-DYSXS20A
  • Utilizes high-performance EFM8BB2 50MHz MCU
  • High-current burst rating
  • High-Resolution Throttle steps
  • Supports 1-2ms signal, Oneshot125, Oneshot42 and Multishot
  • Supports Motors with super high KV (EFM8BusyBee 50MHz can handle up to 500k eRPM)
  • Firmware upgradable via signal wire (works with USB Linker for XM series)
  • BLHeli_S ESC with Hardware generated PWM synchronous to MCU yields ultra-quiet motor performance

DYS XS ESCS is the new generation of multirotor speed controller with the latest BLHeli_S software.

BLHeli_S is an improved version of the base BLHeli code:

  • BLHeli_S delivers a throttle response that is Smooth as Silk, and the main factor contributing to this, is that it uses hardware to generate motor PWM. Two MCUs support this for BLHeli_S, namely the BusyBee1 at 24MHz (EFM8BB10F8) and the BusyBee2 at 48MHz (EFM8BB21F16).
  • BLHeli_S will have the same good Sync holding properties as base BLHeli. Maybe even better.
  • BLHeli_S generally does Startup better than base BLHeli.
  • BLHeli_S does damped light. Only.
  • BLHeli_S has motor PWM that is Synchronous to the MCU master clock, as it is generated by hardware. This makes the motor Silent.
  • BLHeli_S has very Small throttle Steps. The resolution varies between hardware configurations (MCU clock speed and driver type), and is between a nominal 512 steps and 2048 steps.
  • BLHeli_S supports very high motor Speeds. A BB1 MCU will support 350k erpm, and the limit of the BB2 is not yet known, so the code is set to limit at 500k erpm.
  • BLHeli_S supports regular 1-2ms input signal, as well as Oneshot125, Oneshot42 and Multishot. Autodetected when the ESC sees an input signal.
  • Last and by no means least, is Simplicity. If you have a regular setup, just install and go fly (calibrate if your throttle range does not match BLHeli_S default). Or if you need to configure or update, just do so with the Simplicity offered by connecting to your ESCs through the FlightController, using BLHeliSuite and a USB cable."
