Unable to boot when on breadboard (LoPy)

  • Hi guys,

    So i am in the final stages of putting this device into a live environment where i need to control a pump.
    My idea was to slim it down a bit by not using the expansion board (2.0).

    But when i connect 5v (tested with 3.5v aswell) power to my LoPy directly it doesn't boot all the way. It is however drawing about 105mA constantly. My diagram basically looks like this: https://docs.pycom.io/chapter/gettingstarted/connection/lopy.html#wifi

    Am i doing something wrong in my setup?
    Do i need to connect some pins to tell it to boot correctly?

    Thanks in advance!
