Fuhjythy 3D Printer hotbed MOSFET expansion module inc 2pin lead Anet A8 A6 A2 Compatible Black

Hence that issue MOSFET Module is solving existing problems by taking the load off the motherboard. It very often that after purchasing 3D printer (especially in Anet A8, A6, A2) motherboard is all load to heat up Printing Hotbed. That creates fire hazard problems as connectors are not suitable for that high loads. It also solving print quality issues as motherboard is not heavily overloaded with power consumption of heating printbed. It is used not for hotbed only. It is very common that it is used for extruder's heating elements too. MAinly it is to take the load off the motherboard and make motherboard more stable and power interference free.
