I have a power supply that drops input voltage to 3.3V. The 3.3V is fed to the vusb pin on the Boron. The data sheet says the Boron should power up but I don’t get anything. The xenon and argon both come on fine when placed on the board.
I have tried using a battery to allow the Boron to turn on, and then set the input voltage limit to 3000 in software. However, that still does not keep the Boron powered when I unplug the battery.
Is the datasheet incorrect or am I missing something?
