A Sparkfun 9DOF sensor stick seems to need a power supply which outputs 3.5V or more...

Dear Sparkfun,Why does your schematic not show what the regulator is? With no datasheet for this PCB and no notation on the schematic what the regulator is, we have no idea how this device can be powered. Is it expecting 3.3V, or is it expecting 5V? Knowing what the regulator is seems like a pretty basic piece of information…could you rev the schematic to show this info?

It’s a MIC5205 3.3V. This is an LDO regulator, so VCC only needs to be above 3.5V.
