Mosfet breakout-board for 3d printing.
Circuit was tested on perfboard with following components:
*IRF3708 N-Channel Mosfet
*Sharp PC817 Optocoupler
*1/4W Standard Resistors
Input and output voltage can be as low as 3.3V or as high as 24V without damaging the mosfet or optocoupler, you should be able to mix these voltages up in every combination.
The cutout allows a heatsink on the front and a 30 to 40mm 12V fan on the back for optional enhanced cooling.
You can also lay the mosfet flat and use the cutout to stick the heatsink through for a even more slim profile.
