kicad maple is almost ready for the community what regulators are on the maple?
It shows their are regulators on the schematic I was wondering since it is open source and since leaflabs was making a maple I would jump the gun and make one for my sensor project so it could be one board. The prototiping spageti wire mess gets annoying.
Where can I get a parts list that fallows the schematic?
I know kicad can output one no problem but eagle I messed with before kicad and after makeing 2 boards with it I tried kicad and found it easier.

Not sure if this is the version that will ship, or just a preliminary one, or what. Anyway it shows two MCP1703 3.3V regulators. That's a very generic 3.3V, 250mA regulator - just about any other 3.3V regulator that can output a sufficient amount of current should work equally well, although one thing to check on a substitute would be whether or not it is stable with a ceramic output capacitor.
If you are doing precision analog work it might be a good idea to evaluate the specifications of the MCP1703 to determine whether it's adequate for the analog side of your design, or if you need to move to a higher quality regulator.

LeafLabsThis is correct. We had to scale down from a 750mA regulator because of sourcing issues.
We use two regulators in order to provide separate analog and digital power planes and decouple any digital noise from mucking up the analog sampling. This works VERY well when we compare it against the single-supply maple rev1
