Hot bed... (and electronics schematics PDF/PNG's?)

Posted · Hot bed... (and electronics schematics PDF/PNG's?)

Could someone tell me what the low side MOSFET for the Ultimaker PCB is please? I'm pretty sure I have a 1.5.x board

I'd like to run my heated bed from 48VDC but don't want to blow the UM board up.

Also an image export or pdf of the schematics of the sheild would be very useful.

    For reference the MOSFET is listed as an STP55NF05L so should be able to do what I want to do with it.

    ED- scratch that! there's a diode (D3) which is connected to VCC/2 which would cause my 48V supply to feed 48V into the whole Ultimaker circuitry if I did this! This definitely can't be done without addressing this issue at least.
