IRF540 Four Channel MOSFET Switch Module
This board is a four channel mosfet that acts like a switch. Unlike the normal high current switches, this device allow users to send signal from their microcontroller to this board via PWM. An optocoupler will act the buffer to the IRF540 mosfet in terms of voltage isolation. In essence this board will act as a relay module for high current and frequency toggling.
Simply connect voltage source to the power terminal block and your device you wish to power into the four available channel terminal blocks. Using the headers on the connector side, you can interface an Arduino uno to PWM or set a duty cycle for the channel you wish to turn on or off.
