Breakout Adapter for HP Common Slot Power Supplies
This adapter board enables use of an HP (or HPE) Common Slot server power supply with your 3D printer, cryptocurrency mining rig, etc. These power supplies are readily available on the used market at low prices (I've seen 460W models going for just $20) and are more reliable and deliver more power than the power supplies commonly shipped with 3D printers.
Four pairs of screw terminals provide 12V when the switch is turned on. A USB power jack (5V 2.4A) is also provided that is always on when the power supply is plugged in; this could be used to (for instance) power a Raspberry Pi running OctoPrint to control your printer.
This project depends on these submodules:
(The latter is a fork of the DigiKey KiCad library at GitHub, with 3D models added as I need them.)
git clone --recursive https://gitlab.com/salfter/hpcsadapter.git should
pull in everything.
