40A 4-in-1 BLHeli_32 ESC

  • All codes use damped light mode. Damped light does regenerative braking, causing very fast motor retardation, and inherently also does active freewheeling.
  • The code supports regular 1-2ms pulse width input, as well as Oneshot125 (125-250us), Oneshot42 (41.7-83.3us), and Multishot (5-25us).
  • Dshot signaling is supported at any rate up to at least Dshot1200. The input signal is automatically detected by the ESC upon power-up.
  • High-performance 32-bit microprocessor with a running frequency of up to 48MHz for an excellent performance.
  • BLHeli_32 firmware is the third generation BLHeli.
