M5Stack Basic Core w/ SIM800L Module

[ckuehnel]

If I connect the SIM800L module to the M5Stack Basic Core I get always Resets as in the screenshot shown

Is there enough power over the USB connector to source that combination? SIM800L can have spikes till 2 A.

I have connected a GoBottom w/ 600mAh LiPo but that's not enough. What can I do in this case?
