The Lumenier 30A BLHeli ESC with 5v / 1A BEC is a top performing electronic speed controller with fast mosfet driven, dedicated driver chips on a quality PCB. 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 30A BLHeli ESC 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 we recommend you isolate or filter all sensitive electronics to prevent feedback / spikes.
