I'm in the final stages of putting together an machine with a Keling DB25 and Keling 4030 drivers. The schematics say a 5V power supply is required for the DB25. It doesn't say how man amps are required. I have a couple transformers laying around but I don't want fry the board. Any suggestions??
The 5V DC supply to the BOB and the + inputs on the 4030's will be fairly low current. It should be a regulated and filtered DC supply. 1/2 amp will probably be more than sufficient.
