  Nope, nice idea, but the circuit isn’t constructed that way.

  The switch effectively sends a signal to the regulator (via a changing resistance) to tell it what output voltage to produce. Putting a header on the switch would not give you access to two outputs.

  I’m not seeing some pieces information that would be really useful to have before buying:

  • Input voltage range (based on regulator dropout and reasonable current limit)
  • Compatible wall-warts from sparkfun
  • Current limit for board (considering LM317 w/ no heat sink)

  Would be nice if the description mentioned the exact name of the part in the Eagle library. I can’t figure out a way to match them other than by looking at the part footprint to make sure it’s the same. Any better suggestions?

  Yes! Definitely needs 4 FETS.
  I had a miserable time with this thing because the voltage divider line may only work with devices that do not have RX lines pulled up!

  Is the charge rate 500mA? Not sure 500mA/hr actually means anything…

No public wish lists :(
