Blackstar Cicada 20A BLHeli_S 4-in-1 ESC (BusyBee2 chip)

Blackstar Drones

Four superior quality 20A electronic speed controllers with support for the new BLHeli_s firmware mounted on a standard 36mm x 36mm stackable PCB board. BLHeli_S is designed for superior performance in multirotors, and uses hardware generated motor PWM for smooth throttle response and silent operation.

The controller feature the new Silabs EFM8BB10 MCU and Vishay SiS476DN FETs, rated for up to 30V and a max current of 80A are mounted on the underside of the board.

The ESCs come pre-configured with "damped light mode" which results in highly responsive regenerative braking. Software features have been added to prevent sync loss and there are several tunable parameters you suite your flying style and, although the default settings work well for most pilots.

The ESCs support 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.

Motor and power wires are 18AWG but can easily be removed if you choose to solder your motor wires directly to the board.
