Overview

The Lumenier 20A OPTO Little BLHeli Pro ESC (also known as the Little Bee) is a top performing electronic speed controller with fast mosfet driven, dedicated driver chips on a quality PCB. The Pro version also features a new Silabs processor, the F396. This gives superior braking and freewheeling performance. The motor braking exceptionally fast thanks to the Silabs processor along with high quality gate drivers. The ESC is OPTO with no onboard voltage regulator, so you may need a 5v regulator to power your flight controller.

The Lumenier Little BLHeli is signal wire programmable with an Arduino Nano v3 board, or other Silab programmers that are compatible with the BLHeli bootloader.

With all ESC's that have active braking, it's recommended you isolate or filter all sensitive electronics to prevent feedback / spikes.
