Hey guys I have a question about the power for the board. I had a issue that messed up my stepper drive chip. On the board and I sent to pcw and they are a awsome group of people. When I got the board back. And hooked everything up I got to noticing a issue (not due to repair the board was working great) Now my question is...will the board run on 12v power supply?

From the Mesa 7i76E manual:So yes it does work with 12V.
Mind the polarity.
The 7I76E can get its 5V Ethernet, encoder, step/dir and serial interface power from
connector P3 or the on card logic power regulator can be used with unregulated DC power
supplied to TB3. When the on card regulator is used, the maximum power available from
the encoder, serial, and 26 pin expansion connectors is 2A total. If isolation of field power
and logic power is not required, a common 8 to 32VDC power supply can be used for all
7I76E power.Mind the polarity.
