Notecarrier AF V+ pin?

The documentation for the Notecarrier AF says that it is safe to power the Notecarrier by “applying 2.5 - 5.5 VDC to the V+ pin.*” None of the breakout pins are labeled V+.

The V1.7 schematic has this:


Which implies that the pin labeled <VMAIN is V+. However, this is in contradiction to the datasheet that states <VMAIN is an output pin.

When I measure the voltage between <VMAIN and GND (while connected to USB power) I measure 5V. If the schematic is correct, I think I should measure 0V because of the diode. Perhaps I’m missing something obvious, but it appear there is no exposed V+ pin.

Basically, if my goal is to provide power from a 5VDC power source, some other forums indicate supplying the DC via the solar port (instead of using a solar panel). Is that an approved mode of operation? If not, where is the appropriate location to source 5V DC to the Notecarrier?

At least on all my boards Notecarrier AF 1.7 boards, DS2 is not populated with a diode, instead it is populated with two zero ohm resistors.

So the answer is, PIN 12 on J9 is both V+ and VMAIN.
