Richard,
from the ooPIC homepage:
The OOPic-R's 3 voltage regulators are configured so that the logic
side of the board has a private one-Amp power supply, while the I/O
has a full five Amps of regulated power, plus an optional voltage
regulator that can be specified and installed as the end user needs.
A set of power selection jumpers allows different sections of the main
I/O lines to be connected to the various power supplies. In addition
to regulated power, a Servo Power input is provided so that a device
connected to the main I/O lines can be connected to unregulated power
when needed.
So it looks like I am OK without the additional regulator. I did not
realize that it had that capacity out of the box. Is there a way to
test how much power the sensor is using (I do have a Fluke 115 meter
available)?
thanks
