FET Bed Heater Board

[printbus]

On the relay board, I recall maybe a couple of other threads where, in addition to providing a MOSFET switch, the person was adding other useful stuff onto their custom board. For example, adding an ABL servo or a Raspberry Pi Octoprint controller can leave you starved for 5V, so people were adding 5V regulators on their boards. I remember suggesting that providing 12V distribution and a few lightweight MOSFETs for things like fans or lights would be a good idea.
