BLS 15A 4IN1 ESC

EMF8BB21F16G main control chip, dual pad design, operating frequency up to 48MHz. Imported mosfet, three in one IC drive, imported high-quality high-frequency Ceramic capacitor. The high-end PCB production process uses metallized edge wrapping on the solder pads to prevent them from falling off during use; 2-ounce copper thickness, 4-layer plate, greatly reducing heat generation and improving efficiency.
