Hi, this might be a silly question to some.. I've finally soldered all parts for the RAMPS and attached to the Arduino. On the RAMPS board, there's 5A and 11A, I know these are power inputs, but what happens with the power input right below it? (the arduino power) is it still necessary? If so, what is the voltage and A?
I bought a cheapo PSU, it has a output chart of:
484W:
20A --- 3.3V
30A --- 5V
30A --- 12V
16W:
0.5A --- 12V
2A --- 5V
I'm not sure which power cable from the PSU I should connect to my RAMPS. The PSU says it has switching mode supply, so I'm guessing any 2 pairs will work, is that right??
Many thanks everyone.
