  • BusyBee2 MCU (EFM8BB21F16) at 48MHz, (Ref. F330 at 25MHz and F39x at 50Mhz)
  • Hardware PWM, previous software PWM:16KHZ, hardware PWM: 36KHZ with more smooth throttle response and silent operation
  • BB2 can support up to 500k eRPM(F39x around 360K)
  • Damped light/synchronous rectification/active freewheeling
  • Supports regular 1-2ms input signal, as well as Oneshot125 (125-250us), Oneshot42(41.7-83.3us) and Multishot (5-25us). Auto-detected when the ESC sees an input signal.
  • Sync loss protection feature, it will have the same good sync holding properties as base BLHeli.

What is BLHeli_S?

  • BLHeli_S firmware is the next generation code, following the base BLHeli code.
  • BLHeli_S is designed for superior performance in racing drone,and uses hardware generated motor pwm for smooth throttle response and silent operation.
    All codes use damped light mode.
    Damped light does regenerative braking, causing very fast motor retardation, and inherently also does active freewheeling.

  • BLHeli_S code supports features to prevent sync loss. There are tuneable parameters that can make the code run well even inthe most demanding situations, although default settings will work excellently in normal operating environments.
  • BLHeli_S code supports regular 1-2ms pulse width input, as well as Oneshot125 (125-250us), Oneshot42 (41.7-83.3us) and Multshot (5-25us).
    The input signal is automatically detected by the ESC upon power up.

  • Continuous Current: 20A
  • Peak Current (10s): 25A
  • BEC: no
  • Lipo: 2s – 4s
  • Programming: Yes
  • Size: 36 x 36 x 4mm

      Can I power a flight controller with the red/black +/- leads from this ESC’s breakout cable?

      Breakout cable red and black wires are not activated, this is why I’d suggest to cut them off and solder to battery wire pads
