The AT32F421 main control chip operates at a frequency of up to 128MHz. Imported MOS from Japan, three in one IC drive FD6288Q drive, imported high-quality Murata capacitor, using high-end resin plug hole PCB production process, all using metallized edge wrapping to prevent solder pads from falling off during use; 3-ounce copper thickness, 6-layer plate, greatly reducing heat generation and improving efficiency.
