5v supplies for breakout board

[dazza]

Im hoping for a bit of help here,im completely useless with electronics I have a cnc that another lad wired up .
But this time round ive tried to get as far as I can get without posting and cant say im enjoying it lol.
theres an image below of how far ive gotten with it,its for an x3 conversion,feel free to tell me if Im doing something wrong.
the power supply is 68volts and was a kit someone put together a while back for me, drivers are 70v
bobs a cheap kl-db25.
ive overlooked/think I need a 5v power supply to the breakout board and wondered what you recommend I do.
is there anything off the shelf I can use that I could plumb into this supply.giving 5v thanks
