Product overview
The HAKRC 4233-K8 8S 50A ESC is an electronic speed controller measuring 33*14 mm and weighing 51g net. It accepts a 2S-8S LiPo input and has a continuous current rating of 50A, with a separate peak rating of 65A. Its control electronics use an AT32F421K8U7 main chip operating at up to 120 MHz, alongside high-current MOS components and an FD6288Q three-in-one IC driver. The specified ESC firmware is HAKRC-AT4G-Rev.32.9, and the current ratio is 300.
The board architecture combines eight layers with 3-ounce copper and resin-plugged holes. Its double-pad design uses metallized edging intended to help prevent pads from detaching during use, while Murata capacitors are included in the component configuration. The copper and board construction are intended to reduce heat generation. For control signals, the ESC supports PWM, Oneshot125, Oneshot42, Multishot, Dshot150, Dshot300 and Dshot600, providing the explicitly listed protocol choices for its control connection.
