A 4 in 1 version of the the Lumenier 20A OPTO Little BLHeli Pro ESC (also known as the Little Bee), 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 Lumenier Little BLHeli is signal wire programmable with an Arduino Nano v3 board, or other Silab programmers that are compatible with the BLHeli bootloader. (ex. through your flight controller, Cleanflight, Betaflight etc.)

Nice and Compact. Stacks well. Holding up nicely. review by Matt on 2/5/2017
Purchased a month ago. Using with 4S and Cobra 2204 1960KV motors with 6045 props. Performed well with out any initial changes. Extremely small. Stacks well. Using with a PDB below it and Naze32 on top, all fittiing in the center of a ZMR250 frame. Great product so far.
