The AT32F421 main control chip operates at a frequency of up to 128MHz. Three in one IC drive FD6288Q drive, imported high-quality Murata capacitors, using high-end resin plug hole PCB production process, all solder pads are metallized with edges to prevent solder pads from falling off during use; 2-ounce copper thickness, 6-layer plate, greatly reducing heat generation and improving efficiency.
