4 Channel IRF540 V4.0 MOSFET Switch Module

It can supply up to four groups of electronic switches to control different circuit blocks respectively. Limited by the working principles, MOSFET can only be used to control the DC circuit, such as DC-LED screen and so on, but not suitable for AC circuit control. In some extreme cases, It can be used to control a 100V/33A DC circuit. However, it is suggested that the controlled DC voltage is no more than 9V.
