Product overview
The HAKRC BLS 8B 55A 4IN1 ESC is a four-in-one electronic speed controller with a 44 * 44mm board footprint and a net weight of 13.5g. Its physical construction combines an EMF8BB21F16G main control chip, Japanese MOS components, an FD6288Q three-in-one IC driver and a Murata capacitor. The six-layer PCB uses 2-ounce copper and resin-plugged holes, while its dual pad arrangement includes edge metallization on all pads to help resist pad detachment.
Electrical integration is bounded by a 2S-6S Lipo input specification, a 55A continuous current rating and a 60A peak current rating. Control interfaces include PWM, Oneshot125, Oneshot42, Multispot and Dshot150/300/600, with G_ H_ 40- Rev. 16.7- Multi firmware specified. The mounting-hole notation is 20/30.mm-20/30.5mm. For packaging and handling, the package measures 64 * 64 * 35mm and has a stated packaging weight of 52g. The product configuration is an ESC component.
