  • Powered from USB connector I measured:
    Vbat-Gnd = 4.27V
    Vbat_in - Gnd = 4.27V also
    3.3 - Gnd = 3.28V to 3.29V also.

    B0 is shorted by a solder bridge which I intend to use powering the pico from Vbat_in while powering my gps receiver from vbat controlled through the mosfet and b0 one day.

    My pico came from Kickstarter campaign...
