Question
Why on my LRWAN3 node card, when I power it externally on the +E5V tab, the LoRa card doesn't transmit anymore, while when I connect the usb + external power supply it works again?
Why on my LRWAN3 node card, when I power it externally on the +E5V tab, the LoRa card doesn't transmit anymore, while when I connect the usb + external power supply it works again? And why when I remove all the power supplies and I leave the USB cable, the led of the lora card lights up very slightly?
