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
The V1.7 schematic has this:
Which implies that the pin labeled
V+. However, this is in contradiction to the datasheet that states
<VMAIN is an output pin.
When I measure the voltage between
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?
