The Lumenier 20A OPTO Little BLHeli 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. This gives superior braking performance. The motor braking is exceptionally fast thanks to the Silabs processor along with high quality gate drivers. This ESC is OPTO with no onboard voltage regulator, so you will need another 5V source (like a PDB with a voltage transformer) 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.
