Product overview
The HAKRC BLS 15A 4IN1 ESC from Shenzhen Haike Technology Co., Ltd. is a four-in-one electronic speed controller component. Its board measures 32 * 30mm, with a 20mm-20mm mounting-hole pattern and a net weight of 5.3g, providing concrete dimensions for installation planning. The electrical limits are a 2S-4S LiPo input, 15A continuous current and 25A peak current. Supported control signals span PWM, Oneshot125, Oneshot42, Multispot and Dshot150, Dshot300 and Dshot600.
The controller uses an EMF8BB21F16G main control chip operating at up to 48MHz, together with a dual pad design. Its power circuitry incorporates an imported MOSFET, a three-in-one IC driver and an imported high-frequency ceramic capacitor. The four-layer PCB uses 2-ounce copper and metallized wrapping around solder-pad edges intended to resist pad detachment during use. The specified firmware is G_ H_ 20- Rev. 16.7- Multi. Packaging measures 64 * 64 * 35mm, with a listed packaging weight of 18g.
