Could use some advice here, bought a MKR1500 board to experiment with MKR1500.
What I'm experiencing is that the board seems instable when powered only through USB (such as a sketch not being uploaded, but working perfectly fine everytime when batterypack also connected).
But when the USB cable is removed, I can't get it to power on, although pressing reset quickly in succession does make an orange led flash slowly.
I'm kind of lost here.
What is happening ? I'm now worried that this board is so power hungry it won't ever be suitable for demoing / development. (Kind of knocks the fun out of a demo if it needs two powersupplies connected in order to even boot..)
No doubt I'm missing something obvious here.
